Can't help you Howie! I've got a Kennebec that had the same bands - damaged beyond use. I have been looking for a while and have not been able to locate anything
just like it. If you find something let me know! I'm also looking for aluminum bands like those found on my dad's 1960 something Chestnut. I would use them to shave ounces off my lightweight solo model canoe. The Old Town outlet in Maine had them (the aluminum) but wanted much more than I willing to pay ($35 a piece, if I remember right).
Good luck with your quest!
