i have been looking at texaco pump plates on ebay and here and was hoping someone could tell me about the different sizes and how to age one that does not have a date. i found a 15 inch texaco plate while metal detecting, i did see two photos here in the gallery that are the same as the one i found but they are smaller and are said to be from 1939. the ones i saw on ebay were all different sizes except for a 15 inch one, and all were painted just a little different. the 2 i saw here are painted the same just smaller. i will try and upload a picture as soon as i can get one.
