Does Anyone Recognize The Auction House?

I found this in a bulk revenue lot from ebay. Does anyone recognize the auction house from either the numbering system or the description style?

It is most definitely card stock, considerably thicker and heavier than a normal stamp, but what wasn't noted in the lot description is that it's a T15a double transfer.

The stamps do occasionally show up on a really thick paper, I have a $3 Charter Party that is at least twice as thick as normal. Of course the T15 would show up on the proof as well as the stamp.

I'm quie probably wrong. It it looks a lot like lots that I've won from regency....

The style looks very similar to a Nutmeg label:

The fonts are different, but the positioning and numbering are spot on. Thanks!

Possibly: when auctioneers use the Stamp Auction Network website I think they are given access to software that prints their ID and shipping labels. That might explain why your labels "look like" labels from different auction houses. Tom At SAN is a great guy. Maybe he can help. Educated guess is that each auction house has a unique ID # with SAN that appears on anything they print through the SAN software. Or I might be wrong with my "theory"...

On another board the consensus was Nutmeg.

I don't think SAN provides software that prints their ID and shipping labels (at least I know of houses that use SAN that software from another provider).
