For reasons explaned elsewhere the SMGT came home from work one day last week in the car
rather than the more traditional arrangement of under the cyclist.
To fit it in the car the seat is removed. This involves two QR bolts. There are some spacing washers of which two are curved on the inside and flat on the outside type. I realised one was missing whilst trying to fettle it back into shape. Arghsoddit.
I revisited the spot where the bike was put into the car. Just over ½ a week later there in the office car-park is laying one arghsoddit washer, still in the correct shape and ready to be reunited with the rest of the bike.
Yay!
(To restore balance to the universe the network had been tinkered with in the office, disabling the software I work with.
