This is the one I used. Bought it for a Petrographical scope I was restoring, but the knobs were in the way of the objectives. https://www.ebay.com/itm/Mechanical-XY-Stage-40x40mm-Graduations-for-Polarizing-Microscope-w-Rotary-Plate/143116520851?epid=8019378754&hash=item215268cd93:g:L3QAAOSw3v5XIz54...

Re: Easier than I could have believed

Well, the sum total of the “work” was drilling a hole and tapping it to fit the mounting screw on the clip. This one has a nice straight edge that sits 1/4” from the straight edge of the base. I spent a lot of years working as a printer, and recognizing wheather or not two lines a quarter inch apart...

1917 Spencer model?

Trying to find a model designation for this Spencer microscope. Serial number dates it to 1917. From the catalogs I have been able to find, it appears to be an early variation or a predecessor to the model 40.

Re: Revival of old Brasso paste

Brasso really cleans down to the metal. It also efficiently dissolves any finish.
I’ve found it is better to use a light polish with jewelers rouge followed by Renaissance Wax to preserve the lacquer finish and still get a nice shine.

Re: Three B&L “Model” microscopes

I can see no de-lamination at all. All three produce clean images. The only real problem is with two of the three fine focus assemblys. The design used a leaf spring to resist the fine focus screw, but it is a weak point. Time seems to have defeated two of these scopes. Needless to say I am very car...
