742 gears in a 741 case

I wasn't looking for strength I was looking for period correctness and ratio.
Do these gear teeth look functional? from what I have seen the setup doesn't seem to have any chips or major damage to it. there might be some rust pitting on some teeth. never used used gears before, any advice,

Its just such a good deal even if it needs rebuilding if the gears are usable (IE not noisey)
If it needs new gears than its about the same price as piecing it together with new power lock, used case and new gears

I wouldn't worry about it if your not putting a lot of power to it, i have used the same looking gears, just polish the rust off with a wire wheel on a drill and run them, they wont make noise unless you have rusty bearings, I would change them.
