Dear list,

No strictly a confocal question, but maybe somebody can help...

I have an old (maybe ancient) Zeiss microscope. The only identification 
on it is Carl Zeiss, West Germany. It is a binocular microscope with a 4 
position nose piece, a bright field/dark field condenser and a built in 
light labeled "Einbau - Trafo" which translates at mini transformer 
according to Google.  The ocular tube is 22 mm diameter, and the 
objective thread is 20 mm diameter as closely as I can measure it.

The scope generally works fine, but it has two significant flaws:
1. Something in both oculars has started to delaminate and I see 
distinct artifacts of this in low light conditions.
2. The X axis of the stage has broken loose (the ball bearings have 
popped out).

For most of what I do with this scope (showing my daughter things at 
home) it is fine, but it would be nice to have a working stage and clean 
oculars. So if you have any old oculars sitting in a drawer that you 
could send my way please let me know. If you have a functioning stage, 
I'd love to get one; but it's not that difficult to use the scope 
without the stage clip.

Another question: on the body of the microscope, right hand side just 
below the binoc is a small stainless steel nob. If I take the binoc off, 
it reveals a small piece that flips one of two filters into the light 
path (one is always present). I can see no difference in the image 
whether I am in bright field or darkfield mode, so I am ssuming that 
both are currently clear glass. Does anybody know what this piece is 
intended to do?
