I have two 1974 Grand Jubile bikes. They both started as bare frames so there's no mistake about the threading. One has a French BB, the other swiss.

Here's some pictures of one of them after I built it as a wet weather beater. It was a "dump bike" frame that went through a garbage compactor truck! ;-)

BTW, There were supposed to be a few bikes labeled Grand Jubilee that matched the Huret Jubilee derailleurs. The rest are just Jubiles.
