Can anyone tell me if this was ever an original sight on the early Ben Franklin 317 or 322?

I have a different one which is incomplete, missing the screw in eyepiece: http://s133.photobucket.com/user/mag...ml?sort=3&o=12

Does anyone have a spare eyepiece for the second one, (ignore the threaded bit sticking out) and or a complete peepsight of any sort to fit my other rifle (same fitting)?
