From personal experience, I can't see anything for concern with later Viscount forks. I have covered thousands of miles on a 77 model Aerospace Pro which apparently has the most recent iteration of the "death" fork, with a solid steel shaft incorporated into the forged alloy crown (the forks are one piece, beautifully made and, in pre-internet days crack tested when I couldn't figure what the fuss was about). The steerer tube slips over the shaft and is pinned to it (on my bike). Absolutely no sign of a loose connection - which it turns out, was the reason for the recall of the forks (by Yamaha?) which had by that time bought the company. Aerospace Pro frame is chrome moly and makes a really nice base for a rebuild. I've doe so, replacing the mishmash of Shimano, TA and Viscount (Weinmann knockoff) centerpull brakes with pretty much all Suntour Superbe components. Haven't encountered what some say is a fault with the frame in that it's prone to cracking round the bottom bracket - but then I'm probably not your Mark Cavendish kinda sprinter. Last but not least, said bottom bracket is unthreaded with the axle located in interference fit sealed bearings positioned by circlips. Axle is a pretty dodgy looking bit of kit.
