Thanks Max, perfectly easy to follow information!!!
Im very happy to use good quality reproduction parts but if I can get an original part in good condition for a fair price, I'll snap the original up. That's how all bar 1 of the 5 pre 1960 restorations came about, I just stumbled upon enough of the rarer parts at cheap prices (compared to ebay) and now I'm just waiting for a couple of parts for my model 2 and auto but I've got everything for my model 5c, special 5c and my model 8 standard.
