Is a 1912 pulley the same as the common later crank pulley ?

No - a lot smaller diameter.

Parts books show that all are a 3" until 1920. is your query more in regards to that pulley being flat rather than convex?

Thanks Kerry and Steve, the diameter is the main thing I was after. I do have one smaller one.
I have a couple of the newer ones for sale and a fellow was interested in one for a 12 and I thought it would be different. He is in Australia also.

Some earlier ones had four approx 1/4" holes in the back face, and a diamond shaped mark moulded into that face. I have no idea when these were deleted in later editions.

May be a canada/australia thing. Canadian large pulleys had cast & have 6 holes in the back with that diamond mark. Some, many all? dont know.
I just installed one on an American car. I hope it still runs.

John, the 6 hole Canadian pulleys are a different beast. They are the large diameter style and they are a machined casting. The early pulleys are the smaller diameter pressed steel type. The very early ones have the 4 smaller holes in the rear face. Most of the small ones have flogged out pin holes and ill fitting centres. I rebuild these by machining up a new centre and welding it back in place of the worn section.

I forgot to mention they were larger size.
