Here is a link to Classic Rendezvous with a history and
write up (detailed) of Lambert/Viscount.

I won't go into details concerning marketing etc. but notice
the pictures of the "death fork". Someone on CR did an
analysis of the fork and indeed it was a disaster prone design.
I'll see if I can dig up the write up.
But as I've said, I rode one and although I had the fork replaced,
it hadn't failed for the entire time I used it as a daily commuter.
Dave, I don't think Lambert/Viscount killed the boom, at least
not entirely
