I believe there are many more hidden/forgotten in sheds around the country (UK) and certainly, a few more still exist than you mention, There's about 70 ss100 still out there and a fair few ss80 also.
I have heard rumours of a guy in Cornwall with 2 ss100 tucked away and every year some forgotten gems are rediscovered.
Lof A's number 7 was returned to Brough after his accident and repaired and resold
All I have is some of those parts you mentioned hung on my wall of fame. Lots of cool names here.
