[Ford-ferguson] 2N Ford Restore Saga

[Gordon Hart]

My 2N is an early '47 and I have a fan blade for it that I bought off eBay. This fan's blades are rounded on the ends more than the normal fans. I have heard that this type blade was used only on 1939 9N's. Can anyone confirm that fan blades for a 1939 were unique? BTW is the correct one for my tractor a puller or pusher? 4 or 6 blades?

Question number two is in some parts/operators/service manuals it appears that the oil breather cap might have been painted black can anyone confirm that?

How about the starter and generator's color?
