The Stronglight 49D design goes back to pre-war days. Constrictor first
catalogued it in 1938 but I think I remember it being said to be a year or
two older than that. And it wasn't just catalogued and not produced I have a
49D right arm which is stamped Conloy on the back. Conloy was Constrictor's
trade name they applied to any aluminium alloy parts they marketed or made.
After WWII imports did not start to come in again in Britain until 1950 and
the importers were then Fonteyn and not Constrictor. Stronglight had a 5-pin
cotterless steel crankset design out in the early 30s 1933 ore so.
The Stronglight 49D crankset remained current right into the 1980s the
other designs from Stronglight were far less suitable for touring.
