MTB Grand Record Dropout Mystery
This concerns a 1977 Motobecane Grand Record that I picked up at a garage sale a while back.
Part I: The drive side dropout faces are not parallel and that bugs me. I imagine the non-parallel faces are what cause me to fumble with wheel mounting but maybe they do not. I've been meaning to present my problem to the board for advice on correcting this. Do I use a vice or a hammer?
Non-drive side is good.
Drive side is bad.

Part II:
When I put the frame into the repair stand to take pictures for this thread, I notice this bronze/gold colored material on the drive side dropout! What?! Has this dropout been repaired?
A repair? Or did someone spill someone spill some gold paint?

Part III:
So I scrape a little here and there and I remain mystified. The non-drive side dropout has a nice radius while the drive-side seems to have some excess material as if a repair was done. The bronze/gold stuff will chip off with a razor blade like paint but maybe brazing material would also? I don't know. Please advise on next steps. Or...Much ado about nothing?
Brazing material chips of with a razor blade?
Isn't this where it would have broken and needed repair?
Isn't that excess material to the right of the knurled adjuster head?

It looks like the axle fits well back into the dropout, do you really need to fight this battle? The dropout might break through the screw hole.
