Hello I am back into the hobby after approx 40 years away and have created a little branch terminus layout. However yesterday one of the main points failed when the plastic bar between the two rails in the moveable bit of the point came detached from the push/pull lever. I am left with two free floating rails that have some holes in the ends of the metal rails and the plastic bar that looks as if it has lugs that might fit through the holes and tie them to the switching bar. However I have not managed to get it all together and now the little spring has come loose too. Does anyone have a diagram of how it is all supposed to go back together so that I can try to reassemble it all please?
