Response from Arnold.
Hi, Eric,
In my opinion your stamp is not a precancel, but just a stamp cancelled by the killer portion of a machine canceller. I think that these types of stamps, once removed from the envelopes on which they originated, confuse more novice collectors than any other type of cancel. I refer you to the book "Silent Precancels" which can be purchased from the Precancel Stamp Society Catalog Department. Check it out at
www.precancels.com by clicking on PSS Catalogs and then referring to the tenth item down in the resulting list.
Best regards and good luck,
Arnold
