There currently seem to be a lot of 12" round Indian Gasoline pump plates on eBay. I some regards they look genuine, but in others they look suspicious. The font for "GASOLINE" looks irregular and the have a "29" at the bottom. Indian Refining Company didn't start using this design pump plates until after The Texas Company took them over in 1931. (This 29 might mean sign number 29, I guess.) Any thoughts?
