That's great Richard as that means that there should be some spare parts still lying around somewhere.
David, I am still a ways off the electrics but I don't want to leave things to the last minute as I am making quite steady progress now. I hope to have my other wheels back at the end of next week and that is only a few hrs to paint and assemble then it will get turned over an work on that one until it is the same as Wombat. In the two drawings shown, the blue circled are what I have just made and the red it what you are refering to. The other drawing is a complicated spring mechanism that holds the hatch open. I will have to ponder that one on my verandah with a cup of tea for a while

. But your observations are indeed quite correct
