BB that thing looks fantastic! Nice job saving it from the trash heap!

Kind of ironic that you need a front shifter, considering those are like tits on a bull these days. I'm happy to send you some of mine if there's nothing available locally.

That thing really needs a flat bar with bar ends. I think I threw all mine away unfortunately!

Used to be common to braze then in on nice steel bikes, but very normal to use a rivnut also. Looks like that's what you have.

It's common in shops to have the rivnut tool cuz you can use it to...
