Very cool, I would give my left u know what for something like this but there was none to be had, my Dad facilitated my bikes from early on and passed down the mechanic gene so there's that.
I see no reason this cannot be brought back, plenty here and a great starting point. The post is a handlebar stem and a very good piece to have especially if it is an odd size.
The crank and BB are also gold if serviceable.
So while no expert, they are here and will be along to weigh in.
Great find, engage.
PS, please tell me it can fit you.
