Well here be one:
Looks like the danged thing's about 40 years old and apparently.
"The Lambert components were all pretty special. The company really went way out on a limb, rather than buying all the various pieces from the normal sub-suppliers, they made or had made for them, parts of their own design and markings.
No bicycle manufacturer had made grand attempt in the post war cycling scene except possibly the huge Raleigh Company, and in that case not with the sporting emphasis as in Lambert's case. These special parts included sealed hubs, sealed bottom bracket (although the first batches had conventional cup & cone bearings), crank sets, front and rear derailleur , brakes and brake levers, handlebar and stem, seat posts, sealed bearing pedals and a special cast aluminum front fork (more on that later.......!) The headsets, rims, chain and tires were the only off-the-shelf items!"
