When I saw this postmark, I thought the postmaster might still be hung over from celebrating the new year. It looked like it was a Jan 8, 1903 postmark. I thought the postmaster hadn't changed the year stamp, because this stamp wasn't issued until Feb 3, 1903. So I bought it as an oddity.
After some research, in 1903 it seems Ada would have had an Ind. T. designation rather than Okla. This only changed when Okla became a state on Nov. 16, 1907. That would actually make this postmark 1908, but it sure looks like 1903.
I couldn't find any Ada Ind. T. postmarks (or really any other Ada postmarks). Please let me know if I've got my facts straight. I'd also like to see any Ind. T. postmarks you might have.
