It looks possible. I don't know much about the Roosevelt RPMs. CONECA has 10 listings for RPMs in 1964, of which 6 are in a north or south direction.
Looks like an RPM to me. I have the 1983 RPM book by Wexler and Miller and your photo looks like RPM 1 D/D north. Nice find!
Thanks for the info. I got a microscope, going back thru my collection. Its bad getting old I cant see.
Its sad but just a part of life i hate the most. You spend years gathering knowlage and then in your old age when you need them the most someone turns the light down just enough so you need those pesky extra eyes to see what you have seen all your life without useing them. I know just how you feel .
