1960s and completely unused and mint ~ this is an amazing item ~ Sinclair Gas Oil promo ~ measures 7.5" long and 4.25" at the widest point.  Made of cardboard and as near as I can tell from inside instructions you snap your wrist and it fires a paper shot (still attached and will remain attached) of Santa Claus.  See photos for details.  I have NEVER seen anything like this so I'm guessing it's very rare.  If you collect Sinclair, Gas &Oil, Christmas, or even fire arms DO NOT PASS THIS UP.  It is so cool.  Comes from our clean, smoke free home.  FREE SHIPPING CONTINENTAL USA ONLY.  Hawaii, Alaska, PR willbe charged for shipping cost.
