Marc,
if the dates in your quotes are correct John pm'd you on Oct 24 saying he got the record that day. On Oct 29 you accuse him of having the record for weeks??? And if you state "stamped original" in your description you should be able to actually know what sort of stamp it is, e.g. ZTSC matrix, raised x, Frankford-Wayne, etc.
John,
I assume that there is a raised "x" in the run out? I consider it common collectors knowledge that this is a often used run out stamp. If you were unsure you should have asked around before accusing Marc of selling a bootleg.
To be honest, I think both of you haven't done yourself any favours in this case.
