According to GCD the cover is from With the U.S. Paratroops Behind Enemy Lines (Avon, 1951 series) #1 but the contents are from U.S. Paratroops (Avon, 1952 series) #3. IW reprints are always difficult to sort out. As long as no one starts trying to switch out covers and pawn them off as originals, then I think they're safe. I'd suggest keeping them totally separate and denote reprint information in the description. That's just a suggestion though. IW and Super have always been too confusing for me to bother with.
