Viscount 400?

Viscounts are like M & M's (or Smarties for the UK folks). Pick your favorite color and then search for a model. I do like the price, and red just brings out the speed demon in me!

My first Viscount, bought from new in 1980 or '81 was an Aerospace 400. By then all of the Aerospace models were lugged. Mine was in a rather nice powder blue, without the go-faster stripes but with the engraved tops to the seat stays. The frame still exists although it cracked across the bottom bracket shell. I bought a similar silver 400 frame, but with the stripes, which I use now. My original 400 had a fine mixture of equipment: Shimano 600 RD (not ex), Dura Ace FD, Weinman brakes & levers &c. Here's a picture of it:

I meant to add that the '400' model name does suggest Shimano 400 components, particularly as the '600ex' (which I also have - identical frame) did come with 600ex bits.  But I think 400 (and indeed 500) derailleurs are quite rare.  I'm pretty sure that the bike shop where I bought my 400 wouldn't have randomly upgraded the factory-provided equipment.  Perhaps Viscount got a good deal from Shimano on 600 stuff, which had been current since the early 1970s and was probably being outsold by 600ex Arabesque by 1980/81. (I specified the rack, guards / fenders and mirror as additions myself.)
