I recently purchased a Wollensak 1" f1.5 Cine Raptar, but it needs the rear threads / mount (c-mount) portion of the lens. If the lens wasn't in such good shape, I wouldn't be trying to complete it. I was just curious if anyone (by any slim chance) had a "parts" lens or specifically that one part?

Here's a few photos of the lens so you can see what I'm talking about:

Any help would be greatly appreciated. If anyone has a fully working version of the lens you'd be willing to sell, I'm definitely interested. This one may be a lost cause which is unfortunate.
