This sled is one of the original 21 Black Panthers that were produced prior to the 1967 model year. While this Panther looks about the same as the 67s, there are many differences...open drive chain (not a case), non-traditional "rolled edge" on the running boards, aluminum dash panel, 140/141 style fiberglass hood, no tailight, different rear suspension, skis made from the 140/141s, etc, etc. Of interest on this sled is all the old signs of red paint showing through on many of the black parts, maybe being black was a later thought? We are only the second owner of this sled, we purchased it in the early 90s from a man in NW Minnesota. Wayne did a good mechanical restoration of this but cosmetically left it "as-is" so as to preserve as many of the historical aspects of this rare sled as possible. One of the few things that is not original on this sled is the seat, we had no choice but to re-manufacture it. It has a 12hp Kohler 4 stroke engine. Entire sled is in good operating condition. Serial # BP6-4631. Model # BP.
