George N. Saegmuller moved the business of Fauth & Co., G. N. Saegmuller, Prop. from Washington, D. C. to Rochester, New York in May 1905, opening in Rochester in June 1905. The new company, Bausch, Lomb, Saegmuller, apparently continued using the same serial number sequence as had been employed at Fauth & Co., with a transfer of name somewhere between serial number 2,400 and 2,600. The serial number transition between Bausch, Lomb, Saegmuller and the Triple Alliance instruments, which took place on January 1, 1908, took place at about serial number 6,750, although it seems extremely doubtful that Bausch, Lomb, Saegmuller produced more than 4,000 instruments in two and a half years. No explanation can be given for this disparity at this time, unless Bausch, Lomb, Saegmuller also numbered all its military output with its serial numbers. (Later military production used different serial numbers.)

The following Bausch & Lomb microscopes have been optically and mechanically refurbished by our factory trained technicians. 1 Year mechanical warranty included. We have thousands of used Bausch & Lomb microscopes and parts. Not all are photographed and documented yet. Help in I.D.ing a Bausch & Lomb Microscope - posted in Cloudy Days & Microscopes: Recently picked up 2 of these Bausch & Lomb Microscopes. I was hoping someone could help with telling me the model number? Also an approximate age. A bonus would be if someone could steer me towards instructions on their proper use also. Thank you in advance. Im at a loss with my research on the internet.

The highest recorded serial number on a Bausch & Lomb surveying instrument is just over 12,000 on an instrument owned by Bausch & Lomb. If Bausch & Lomb manufactured instruments under its own name for a ten year period, the output would be approximately 550 instruments per year, but it must be noted that some instruments have two serial numbers. For example, the trough compasses on Bausch & Lomb's plane table alidades are also serial numbered. As a result, it's most probably fair to say that Bausch & Lomb's output averaged about 400-500 instruments per year. ~Thomas Garver
