Hey, thanks Larry. Their catalog isn't online, but there are a few sources to find the part numbers. Including calling and talking with their staff there at Jack's. And I still haven't finished researching the similarities among the guns mentioned above. But here is the URL for Jack's.

I'll be checking this out further. One of the suppliers has got to have the parts from one of the guns, somehow. Even if it isn't actually the 67 or 69 part numbers.
