I have a 74-75 GJ with Huret dropouts. Here is interesting thing, mine has 57cm seat tube and 58cm top tube measured c to c, which I measured three times. I do not know the head and seat tube angles, but from looking at it the head tube is steeper than the seat tube and they are too agressive to be 70°.

I do agree the bike is surprisingly responsive, but I found the handling to be on the twitchy side at high speed.

I have pictures of 71-73 Moto catalogs. I will post them if anyone want them.
