Until recently, Stephen, I had my original S1 wiper arm getting in the way in the garage. For that very reason it went to the tip a couple of months ago, sorry! However get a late style S2 arm from Eliseparts, way better in any case.
I do however have a pair of original window winders...only the placcy variety, mind, but you are welcome to them if you wish. Let me know and I'll try to rake them out the Parts Bin

Dettol Antibacterial spray will do you nicely...gets into all those nooks and crannies!
