Colombia Departmento Panama with a Black bar overprinting
Colombia and "Republic de Panama" overprint in cursive a bit below the bar.

Without the overprint, it is listed as Panama # 3, and as commented in prior posts on SCF, it is know as not being listed under Colombia. It was printed by the American Bank Note Co, who also added the overprint, under contract with Colombia for use in the department of Panama. Department is known in the US as being like a county within a state.
BeeSue first presented this question in 2010:

Can anyone explain why this stamp and similar ones inscribed Colombia are listed in Scott under Panama. I realize the map is of Panama, but Panama was not independent until 1903.
On her thread, "wt1" left this most informative link
http://www.danstopicals.com/panama1.htm & further down the thread, "smauggie"also posted excellent info concerning her question.
After a lot of searching on the internet, a catalog number for this stamp is still unknown to me. I have seen a few of the 50c of this series of stamps within a group of stamps, listed on
ebay, without reference to it's ID or a catalog number.
I know that one of you will identify this stamp for those interested in Panama and Canal Zone stamps.
Thank you in advance.
PS: I know that this is a long post and I could have simply uploaded the stamp and wrote, "ID this please" and let it go at that, BUT, I thought it would be nice to bring interested parties up to date.
