Thanks to Joel for the Cruzet lug info - though now I'm confused !
This style of lug often turns up on pre-war (and some post-war) Flying
Scots, and I always assumed they were by EKLA - for no other reason,
than that was the name for them that I was given some years ago, and a
couple of diagrams in Brown Brothers catalogues. They look not unlike
those by Cruzet. not exactly those in Joels advert vis;
http://www.blackbirdsf.org/crozet.jpg as there are no cutouts to the
front of the head lugs perhaps peculiar to this particular model, but
in other aspects they seem the same.
I've placed the extracts from the Brown Brothers catalogue on this
temporary page
http://www.flying-scot.co.uk/frame_dtl_pages/lugs_ekla_detail.html
for comparison. Interesting is the footnote to the 1939 diagram "These
fittings are made by one of the finest Continental makers and are used
by most of the well-known Continental riders"
It may well be they are Ekla and Not Cruzet. Without the obvious "AC"
stamped on the lug, can anyone tell ? It may well be that many of the
lug makers followed generic popular patterns, and the difference was in
detail.
Any thoughts ? or has anyone got an 'Ekla' catalogue for comparison ?
