These Colt leather slings come up for sale periodically. I have seen three for sale over the last year and have dropped out of bidding on them each time. I would really like to have one for one of my Colt HBAR rifles but the timing of the sales that I find is never good. This example sold on Gun Broker 19 JAN 2020 for $260 (winning bid) plus $13 shipping. Total cost $273. That is pretty crazy price for an old sling. But, as we all know, Colt collectible items come at a constantly changing market price.
