127 Rodenstock Ysar in Prontor 1 + also a Compur 0
A little 2-fer. Sold seperately, just trying to be thrifty with the ad space. Both CHEAP!
Rody Ysar. Some of these were emitters according to legend. Don't know if this one was. I believe the earliest Polaroid CU-5 cameras came with these.
Prontor 1 shutter is flawless, as is the glass. This covers 4X5 and is OH SO SHARP! $55 + shipping
Next is a Compur size O shutter if you need one..........but.........you'll have to fix it.
Escapement timing sounds flawless, but the blades do not open. Must be a hair spring undone from a doomeflaget in there. $28 + shipping
Both of these have a retainer, even though not shown.
