Pianos with Kohler and Chase serial numbers range from the year 1895 to 1957. Kohler and Chase outsourced the manufacturing of the instruments sold in their stores. Although they were a west coast company, they had their pianos made in New York by a few different manufacturers. Their vertical pianos were made by the Ernest Gabler Piano Company, grand pianos were built by Jacob Doll & Sons, and their top of the line Andrew Kohler piano was made by Wellsmore Piano Company.

The Kohler & Campbell piano that was given to me was an upright grand, serial number 163634, which dates to 1902, meaning this piano was built when the company was only eight years old, and it was 113 years old when it joined the Encore! family. Unfortunately, it suffered much water damage while in storage, but I was able to use the keys and the action. I still have many pieces of the case, but have not tried to restore them. Soon I will.
Andrew Kohler Piano Values By Serial Number
The Pierce Piano Atlas lists a Schnabel, Ludwig, Austria, at Prague. It also lists Schnable & Hints, or Hintz, in 1876. That is the only information. The vast majority of pianos in the Pierce Atlas have lists of serial numbers with corresponding dates of manufacturer. So, these are extremely rare pianos. It is possible that it is a stencil piano. Schnabel is a more preferable name on the piano than some Chinese city and the company is long gone so there would be no legal hassles in using the name.
I recently came in ownership of a Vose & Sons Upright Piano (serial # 43074) I was told that it has the original ivory keys and may not have ever been restored. I know ablsolutely nothing about pianos. I am looking to sell the piano and could use some help.
Hi,I am quite interesting on one YAMAHA LU-90 PE upright piano.The serial number is#1537147Asking price is AUD 2500.There is on chip on the bench and scrach (fading color on one black key)Could you please advise the price range about this piano?
While I am not familiar with Zeitter Winkelmann, from the serial number, the piano was manufactured in 1928. So, condition is paramount to the value of the piano. Also, whether it is a grand piano, upright and what size, finish and other details will determine the value of the piano.
Petrof pianos are manufactured exclusively in Hradec Kralove, Czech Republic, see It is a company with 140+ years of history in piano making and all instruments have a great deal of hand made. To my opinion, these piano can fully compete with other europian and american brands. Petrof is holding many important patents on pianos and their flagship P284 Mistral can to my feeling compete with D274 Steinway top model (As the model number suggest, the Petrof is 10cm longer than the Steiway).
I have an Irmler piano with serial number 19403 which roughly corresponds to the year of production 1911-1912. The piano was produced in Leipzig, Germany, but not in China. Some serious companies selling pianos even are not aware of the fact.
In the radiology department of the Mexican National Institute of Neurology and Neurosurgery, a dedicated institute in Mexico City, on average 19.3 computed tomography (CT) examinations are performed daily on hospitalized patients for neurological disease diagnosis, control scans and follow-up imaging. The purpose of this work was to estimate the effective dose received by hospitalized patients who underwent a diagnostic CT scan using typical effective dose values for all CT types and to obtain the estimated effective dose distributions received by surgical and non-surgical patients. Effective patient doses were estimated from values per study type reported in the applications guide provided by the scanner manufacturer. This retrospective study included all hospitalized patients who underwent a diagnostic CT scan between 1 January 2011 and 31 December 2012. A total of 8777 CT scans were performed in this two-year period. Simple brain scan was the CT type performed the most (74.3%) followed by contrasted brain scan (6.1%) and head angiotomography (5.7%). The average number of CT scans per patient was 2.83; the average effective dose per patient was 7.9 mSv; the mean estimated radiation dose was significantly higher for surgical (9.1 mSv) than non-surgical patients (6.0 mSv). Three percent of the patients had 10 or more brain CT scans and exceeded the organ radiation dose threshold set by the International Commission on Radiological Protection for deterministic effects of the eye-lens. Although radiation patient doses from CT scans were in general relatively low, 187 patients received a high effective dose (>20 mSv) and 3% might develop cataract from cumulative doses to the eye lens.
Knowledge of the composition of urinary stones is an essential part to determine suitable treatments for patients. The aim of this research is to characterize the urinary stones by using dual energy micro CT SkyScan 11173. This technique combines high-energy and low- energy scanning during a single acquisition. Six human urinary stones were scanned in vitro using 80 kV and 120 kV micro CT SkyScan 1173. Projected images were produced by micro CT SkyScan 1173 and then reconstructed using NRecon (in-house software from SkyScan) to obtain a complete 3D image. The urinary stone images were analysed using CT analyser to obtain information of internal structure and Hounsfield Unit (HU) values to determine the information regarding the composition of the urinary stones, respectively. HU values obtained from some regions of interest in the same slice are compared to a reference HU. The analysis shows information of the composition of the six scanned stones obtained. The six stones consist of stone number 1 (calcium+cystine), number 2 (calcium+struvite), number 3 (calcium+cystine+struvite), number 4 (calcium), number 5 (calcium+cystine+struvite), and number 6 (calcium+uric acid). This shows that dual energy micro CT SkyScan 1173 was able to characterize the composition of the urinary stone.

If package counts on abdominal CTs of body-packers were known to be accurate, follow-up CTs could be avoided. The objective was to determine the accuracy of CT for the number of concealed packages in body-packers, and the reliability of package counts reported by body-packers who admit to concealing drugs. Suspected body-packers were identified from the emergency departments (ED) database. The medical record and radiology reports were reviewed for package counts determined by CT, patient-reported and physically retrieved. The last method was used as the reference standard. Sensitivity, specificity, positive predictive values (PPV) and negative predictive values (NPV) were calculated for CT package count accuracy. Reliability of patient-reported package counts was assessed using Pearson's correlation coefficient. There were 50 confirmed body-packers on whom 104 CT scans were performed. Data for the index and reference tests were available for 84 scans. The sensitivity, specificity, PPV and NPV for CT package count were 63% (95% CI 46% to 77%), 82% (95% CI 67% to 92%), 76% (95% CI 58% to 89%) and 71% (95% CI 56% to 83%) respectively.

To assess the correlation between the enlarged vestibular aqueduct (EVA) diameter and (1) the hearing loss level (mild, moderate, severe and profound and (2) the hearing evolution. The secondary objective was to obtain measurement limits on the coronal plane of the temporal bone CT scan for the diagnosis of EVA. Retrospective study in a tertiary pediatric center. Mastoid CT scans were reviewed to measure the VA diameter at its midpoint and operculum on axial and coronal planes in a pathologic and normal population. We used their serial audiograms to assess the evolution of hearing. 101 EVA was identified out of 1812 temporal bones CT scan from our radiologic database in 8 years. Bone conduction was stable after a mean follow-up of 40.9 32.9 months. PTA has been the most affected in time by the EVA (p=0.006). No correlation was identified between impedancemetry and the diameter of the EVA. On the diagnostic audiogram, 61% of hearing loss were in the mild and moderate hearing levels; at the end of the follow-up 64% of hearing loss are still in the mild and moderate hearing levels. The cut-off values for the coronal midpoint and operculum planes on the CT scan to diagnose an EVA are 2.4 mm and 4.34 mm respectively. Conductive or mixed hearing loss might be the first manifestation of EVA. Coronal CT scan cuts can provide additional information to evaluate EVA especially when axial cuts are not conclusive.
