These bags would be RARE and hard to find, they came off my 1966 HD 250 Sprint H, I've also seen pictures of them on a Harley M-50.  They were purchased through the Harley dealer in Salina where the bike was bought in 1966.  The top is leather and the rest of the bag is a harder plastic.  As you can see in the pictures the hard part of the bag has "yellowed" but could be repainted, it also has some embossing on it.  On the back of both bags is stamped the month and year they were produced, July of 1965.  One of the curved mounting brackets is missing but could easily be fabricated.  Also included is the instruction page for mounting the bag and I would say that by the picture, Harley also had a soft version of the bag.  If interested in talking about them, contact me back through this site or call 785-658-3687 and leave message, I will get back to you.  Could bring to the Great Bend or Salina area.  Thanks for Looking!!!  MAKE AN OFFER
