I have one of these. Anistigmat Special 127 f4.5 lens in a No 2 Supermatic shutter. Speeds are T B & 1-400. The lens elements look good to my eye. Shutter speeds sound and look to be very close. The bellows are weak and need patching or repair. I would sell it for $50 plus fees. Let me know if this is of interest to you. I am located in Medford, Oregon.
