1 Stamp, 2 Sellers, 2 Countries

Just wow

Ask both for a scan of the back. The one who sends you it has the stamp

I have heard of dealers who owned brick & mortar stores both in the UK and on the Continent, so perhaps this is a similar situation where one dealer is servicing two markets with the same stamp? But yeah...it smells fishy...

I don't think this is uncommon in the USA either for dealers to operate several ebay store fronts, this morning I left feedback for a couple stamps I bought from two different ebay accounts, a few moments later I received the exact same feedback worded exactly the same and posted at exactly the same time from them. I won't say who they are but think it is just someone trying to get a leg up on ebay search results etc. Both stamps were reasonably priced and represented honestly.

Just for fun I asked both of them a scan of the back, none of them have reply

So the consensus is no funny business here?
