Amazing job on the Sinclair pump! All your pumps look really great. Makes me want to get started on my '61 Wayne 420 pump. Is that blue and white Pure oil pump an A.O. Smith pump? Looks similar the Wayne 400 style pumps.
Thanks! Yes, it's an AO Smith L-3. It's not a very desirable pump (technically neither is the Gilbarco) but I've owned three of the L-3's and they're nice pumps. They're fairly inexpensive and look great when they're done. Here's a better pic of it.
EDIT: I just realized that you were looking at the Purol pump I sold last year. That was a cool pump that I sold to a friend. Here's another pic of that one too.
