I figured it wasnt real as I know of only one good date for these. Thanks for confirming what I thought.
Auction says "GUARANTEED ORIGINAL STAMP". I guess somebody is going to pay over $1000 for a restamp.
You have to be very careful how people word things, especially on Ebay. If the seller stamped an unstamped distributor, then he could claim "guaranteed original stamp". The true original ones I've seen usually say "guaranteed original factory
stamping". My advice is to do your homework and ask a lot of questions, as you have done by starting this thread. Good luck finding one.
