Watsonian pulma help needed

I am working on my watsonian pulma sidecar which will be put on a 1954 Norton big 4 600cc single. I am looking for parts info on the frame. I need to replace bearings and freshen up the rest. does anyone have info on part numbers and exploded photos?? Also I am in need of any photos of the sidecar insides. I have some parts that I can copy but would like better photos on the inside trim seats and any other brackets. Anyone else in the states with a pulma or a monaco?? I"m in The Twin cities up here in Minnesota.
thanks for any help
