Wes looking back through your post you ask about the wood shiping box, had anyone seen the gallon can. You could very well be looking for a can that only reads Pierce oil co.S.A.. I have found some items mostly paper that proves they retained the Pierce Oil CO. S.A. in Mexico. Used along with the Rooster logo.How long? Still working on that. Check out this completed ebay listing 261796905164- 1930 sinclair map of Mexico. Hey maybe you won it!
Hope this helps.
