I've used a 4x5 camera for over 15 years. My family is very big into Christmas giving and presents so this year we came to the last gift to be opened. It was a hug box with my name on it. I unwrapped it and inside I found a custom camera box containing a 8x10 Ansco in great shape, 3 8x10 holders and a lens!!! Needless to say, I had a VERY merry Christmas

The only problem is that I can't tell what size the lens is. The lens is marked :

8x10 Turner Reich Anast. F7.0 Ser II 210251 Gundlach Manufacturing Cotp. Fairport, NY

Its mounted in a Illex #4 Acme f7 - 64 shutter.

Can anyone give me any information about this lens or tell me how to identify it?
