Need Stamp ID Help Please?

OK my buddy found a pile of old stamps and a few look like this. They are not anything that I collect but I was unable to locate this in any of the reference materials I have (eg. Scotts PDF on discs) So I was hoping one of you World Wide collectors could I.D. this for us? Is this a forgery? because the only one I could find that is similar has an overprint and duly notated that forgeries exist? Unsure about it all...lol
Thank you again for any information you may have. Sincerely -Jeff

Armenia
SG0197 [2m0] File4765_2.jpg

So it's Armenia S.G.#0197 correct?

Apologies Jeff,
was called away.
Yes SG197 (I employ leading zeroes for aiding continuity)

Exist perf and imperf.

Your ref possibly Scott 279

Looks like a computer made copy of the stamp.

Why do you say that floortrader?

Can anyone identify these stamps and is there any reference sites I can search by cat # to get country Thanks

They are Bulgarian stamps (from 1919) overprinted in 1920 with surcharge for "Prisoners of War Fund" (SG). In Scott they would be listed under the semi-postal section (which I suppose those B numbers refer to).
