My interest in Apache books is based on the excellent work by Stanley Pitt, not forgetting the nowadays obscure characters they published at the start of the run.
I'm sorry my attempt to help you was of no use.
If it's of interest, and it probably wont be, the British Guide doesn't mention, apart from Mystic, any EC reprints in the comics you show on your site. Obviously wrong, although it does list the Atlas, Prize, Harvey, etc. reprints in those books. Perhaps they didn't think it worth mentioning.
