Anyway the activities of the cast and crew provided suitable entertainment as I continued work on the Vanfit at the other end of the station:
The planks on the right-hand side were fixed in place and a plan devised to replace the lowest thin strip - this will be left until last.
I then started to break out the two lower planks on the left-hand side.
Unfortunately the wood behind the metal end piece had rotted. These rotten remains put up a lot of resistance to being removed and slowed progress to the extent that time ran out on me and I had to pack everything away before I could finish. However the replacement planks are cut to length, ready to go in barring minor fettling.
