Thanks, Guy.

The catalog has 61 pages (!) and includes bridges, seat lugs, bottom bracket shells, frame design drawings for use with their lugs, fork crowns, fork ends, rear fork ends, cable guides and clips, reinforcing parts for seat stays, parts for luggage carriers, moped petrol tanks, yada, yada...

I could scan and post a few other pages if anyone's interested, but I thought the head lugs would be of widest interest.
