A few years ago American Optical was acquired by Leica.  Bausch & Lomb, 
Cambidge Instruments, Reichert-Jung, Leitz and Wild products are similarly 
now part of Leica.  

If you need information on a particular instrument or product, you might be 
able to get the info through Leica Microsystems' Customer Service number at 
1-800-248-0123.  

A lot of the older AO products are now serviced and supported through a 
network of third-party service providers, and your local Leica rep or 
regional dealer can probably put you in touch with someone in your area.  If 
you have problems, just drop me a message.  

Good luck!
