Another "rare modern" (thanks to Brent for that term, as well), these CD 155 Armstrong pieces, in the  embossing style, are marked with "KPP" in a circle before "ARMSTRONG". The KPP is an acronym for "Kerr Packaging Products", and I have been told that this embossing style does not turn up too often. I have managed to locate a few on one short stretch of poles along a local line, and I'm passing this one along. The date code on this piece reads 1972 - '68' followed by 4 dots.
The condition of this piece is essentially flawless. I can't see anything wrong with it.
I'm asking $10.00 U.S. plus shipping for this one. I accept PayPal, and personal cheques or money orders from any member of ICON, or anyone I've dealt with before. Please feel free to email me for more photos, or with any questions. I encourage you to look through my "For Sale (Not Sold)" stock, and combine items to save on shipping. All the best!
