Chris,
Can you identify your general microscope at the following Zeiss site? Is
your microscope black enamel, or dove gray in color?
https://www.micro-shop.zeiss.com/index.php?s=44986906abf985&l=en&p=us&f=c&a=s&data[t]=MCD&data[p]=100&data[c]=c1330

I have one of the black, enamel Standard WL models, and might be able to
send you a user manual or parts information if I have anything matching
your model.

Regards,
~Gregg
