I can't quite make it out, but there should be some text on the lens surround, either the name of the lens (apotar/solinar) and/or the name of the shutter (probably pronto or compur or something similar.) Alternatively, could you take a close up shot of the front of the lens and post it?

Which model of magic is it ? The 1st or the 2nd one ? Does the meter work ? Does the auto exposure work correctly ?

I'd offer a neat 140 for it. Bit on the heavy side for what I might need it for but I'm definately 140 worth of interested !
