Zeiss Winkel microscope

The previous homeowner found out that I am a veterinarian and left this microscope for me, nearly 4 years ago. I moved in immediately prior to my starting my residency, so I never even opened the box before tonight. Of course, I don't know anything about this scope, except that it lights and magnifies. Hoping to learn a little more, so I'm posting photos and will ask some questions on a microscopsy yahoo group website.
