There are a couple of interesting Simmons items on eBay UK at the moment - Simmons bags, new old stock, several available - and a Simmons interface cable for a Commodore 64 computer (no software, unfortunately).
Thought these might be of interest to someone, I've not seen either before.
Spooky coincidence - I live about 50 yards from the site of the old Simmons factory near the mill in St Albans. Recently I got a new job, and I've just realised that the office is... about 50 yards from the site of the old Simmons factory in Alban Park (near the original building in Hatfield Road).
