Primarily Petroliana Shop Talk Forums Thread Like Summary - 7 1/4” Round Sinclair Plate

Does anyone know what these little 7 1/4” plates were used for? A member in another group was told they are “blanking plates” and he says he has the same kind from several other gas brands, but he doesn’t know what they were originally used for either. The hole placement seems very specific. Thanks.

not a chance in hell they are original from any of those companies.................. and im not even anykind of an expert!

Shell used a 6" porcelain on reps vehicles at one time.
