Featured Microscope, info needed

Hi everyone,

This microscope was my grandfather’s. He was a surgeon. It’s Bausch and Lomb Rochester. Any information would be helpful as to what kind of microscope, a guess on the year etc! The patent date marks vary.

Thank you

 

It's a compound microscope, usually used with slides etc for viewing all kinds of items medical or other. If you check the eyepiece it should have the magnification factor on it, usually 5-20, then multiply this by the 'x' number on the objective and that gives you the magnification. So if the eyepiece is a 10, then using the 43x objective gives you a magnification of x430. The 'turret' bearing the objectives rotates, and you can change the objectives by unscrewing them. Looks like there is a light (or focussing lens) under the table to illuminate slides from underneath.

Looks like it has a geared x-y table as well, must had been quite a fancy model in it's day, the maker is known for quality products and I think still in business today.

 

that's a nice piece.....well cared for...with all the bells and.......

 

Great condition. Looks almost brand new.

 

Thank you for taking the time to relay all of that information! Greatly appreciated

 

The booklet probably came with the microscope, and may have a publication date inside, which would be a good indication of when your grandfather bought it.

 

According to this page, it appears this particular microscope was made in 1931 (provided the 232532 is the serial number):

This advertisement from 1931 looks like yours:
