Yeah, I don't think my lens is removable. Doesn't look like it. On the rewind portion, there is are two letters CK. Looks like it would move somehow.

I too searched Ebay and camera quest. I see the PC sync for flash and I have figured out two out of the three letters on the side (used for flash).

Its a 45mm 2.8 lens which is pretty cool and I also have a Sekonic light meter which I guess I can use. My mom has the original Agfa lightmeter, but not sure where....

Cool stuff I tell ya. I am going to roll some 125 FP4 film tonight and fire off some shots tomorrow...

Oh and my camera is know as the "Brightline" model....
