Is there any way to tell the difference between a repop Sinclair porcelain pump plate and a repop Sinclair pump plate? I have a friend that recently picked one up and I let him know I'd check with the board and see...The plates I'm referring to are the std Sinclair pump plates with dino in the center (I am fairly certain the diesel plates have not been reproduced). Thanks everyone
