There are not enough brown-ink backs to affect any population numbers, Ken.

I believe only a relative few are known - slightly more than the number of T207 Red Cross - and not more than 1 of any specific player as far as I'm aware (which is admittedly not very far). The ones I've seen are Factory 240, but I have read that they can be found with Factory 606 back. That said, and though the source is very credible, I haven't seen one, or an image of one, so will reserve judgement till I do... so for me, they're still Factory 240 only.

While they're pretty obvious in person, scans of the brown backs can be deceiving - many posted on eBay as "Brown print" are just as likely not. Scanning cards side-by-side can help with scanned image questions.
