I just picked up a Butcher Popular Pressman 3 1/4 x 4 1/4 SLR (like a Graflex Series B). It's in great shape except the focal plane shutter...it has been removed. The spindles on which it rotates are still there as well as the hardware to wind it just not the curtain. Is there anybody who does this kind of repair work? Am I just going to have to use a lens cap as a shutter? Any ideas?
