Some mechanic might have put a liberal amount of grease in the BB shell and also in the head-tube prior to assembly. Then copiously greased the seat-post as well. Grease has a tendency to migrate, especially in hot weather and move to the strangest places, the bike may have been stored upside down, head or tail-up. Think of it as a gift from whoever put it ...

My life has been such, living in this corner of the world, where it simply hasn't been an option to buy new. And growing up here in a world before internet, if Lakeside Cyclery or Sears didn't have it, you weren't getting it anytime soon no matter the cash-flow. So...

Not really, given you presumably only got this far in the first place because you want things working right. It will never be able to take a good adjustment again and it will get gradually worse, even with more preventative overhauls from here on. The nature of a cup and cone bearing system is that with pitting on any part, by the time you've adjusted it ...

French BBs are usually right/right and ...

I also have a Motobecane Spécial Sport and believe it must date back to somewhere between 70 - 73. I've seen a couple more of them here & there on the web but none of them in catalogue scans!

You're probably not going to find the freewheel remover for a reasonable price easily for this freewheel (and its probably going to be a 1-time use item). Though it probably doesn't hurt to ask around. It looks like you cut the hub out of the wheel which was a big mistake -- it makes it a lot harder to remove the freewheel from the hub. Anyhow, you can ...
