I do
not think they were mutually exclusive, just that at some point during the print run the cards were swapped. It could have been half way through several brands being printed.
I also am not sure the confirmed listing on T206resource for Ames AB460 & UZIT are correct, originally I thought its possible Ames was subbed back in for Tinker but with the recent P42 Tinker find this no longer fits. Would really like to see scans of these two cards.
Recently Dougherty was found with RH, which could explain why no Ames has been found.
