Another piece of information to give you some perspective. When I damaged the top lens of one of the oculars of the IF Fuji, I sent the whole package to Cory to see if he had a lens in his collection which would fit. Meanwhile the Fuji monocular arrived, and although the housing was in rough condition, the lens were OK. After a period of time elapsed, it appeared Cory would be unable to come up with the lens replacement (hardly a surprise with a half century old piece) I decided to "cannibalize" the monocular and use the ocular with the IF binocular. So Cory returned the ocular piece. Does this make sense?
Another piece of esoteria for you "do it yourself" folks. As you know dissimilar metals will result in galvanic action and break down the threads of screwed in pieces over time, particularly in salt air environments. My experience with many old Japanese binoculars where aluminum and magnesium (not really sure what alloys they are) will make assembly and re-assembly difficult in screwed in components. This was true of the ocular housing from the Fuji monocular, but I managed to screw it in with some care, gritty feeling all the way.
Remember, I'm an old man who has been playing with this old stuff for over 60 years.
