Hi Mike,
Yes, I think Trusty was the bike company that bought Lambert's assets went Lambert got into trouble, and Viscount was the brand name used. To begin with at least, Aerospaces were constructed from the same tubing, on the same jigs and using many of the same components as top of the line Lamberts. I love the chainwheel too - one of the many things that makes Aerospaces look so distinctive. Anyway, here's the spec list:
Frame: Viscount Aerospace Pro, 23 inches (well, near enough) crank to top of top tube
Fork: Viscount one piece aluminium fork with steel steerer
Headset: I'n not sure, but I think it might be another Viscount bit...
Stem: Viscount aluminium
Handlebar: Viscount / Copal Foundaries aluminium
Bar Tape: Tressorex black cloth
Brake Levers/Brifters: Lambert aluminium, blue anodized pivots
Brake Calipers: Viscount centre pull
Brake Pads: Fibrax
Shifters: Shimano
Front Derailleur: Shimano Titlist
Rear Derailleur: Shimano Crane
Cassette: 15 - 24 5 speed
Chain: Black and greasy
Cranks: Viscount aluminium cotterless

Bottom Bracket: Viscount, press fit sealed bearings

It's a bobby dazzler alright - I was out on it last night and it really does love going fast.
