I've seen pictures (e-bay auctions?).
Here's what I've been able to further ferret out.
The british build Anquetils had english threading.
imported/exported etc. by Ron Kitching. There were
french versions (french threading) believed to be built
by Gitane. One collector and keeper of list of builders/bikes made some mention of Belgian origin (not
sure why, will try to contact him).
Many different levels of bikes, mostly gas pipe frames with ok parts (Campy Nuovo tipo, Gran sport etc.) but
some were very good bikes (like rare pista models).
Very little info out there on these bikes.
