I received a vintage Spartus 35F 35mm camera in the mail the other day. The seller didn't know what constituted a working shutter, obviously, so I'm stuck with a camera that shoots in "B" function only, and has a stuck yellow filter because the aperture wheel won't move. The rest of the camera is in good condition, cosmetically, so I thought I'd look for another camera with a similar shutter (single speed, very much like a box camera's rotary shutter).
Here's a pic of the camera in question (stock photo):

I knew that Spartus based the body design on the 127 cameras of this design:

So I went looking for similar ones on eBay, thinking that perhaps I could take the shutter assembly out of one of those and install it in the Spartus.
In my searches, I found this one (also a 127), which appears to have the exact same mount:

And I thought: Why not remove the entire shutter/lens assembly from this Falcon, and install it on the Spartus? The mounts look very similar to me, except inverted (one's round on top, flat on the bottom, the other's in reverse, with which I don't see a problem).
I ran this past Doctor Larry already and he isn't sure if a problem would arise from a transplant of this nature, so I put the question out to my other medical colleagues: Do you see anything wrong with such a procedure?
