Your BAR belt appears to be modified to the M1937 style BAR belt. The original wide buckles removed and wide loops attached to the back to accomodate a narrower belt. The two front pouches on the right side are different than the rear....rounded flaps vs pointed flaps. It is possible that the Cup and M1911 mag pouches were removed and replaced with BAR mag pouches...which was common. WWI period BAR belts I've seen sell for up to $150. I think that your belt, with the possible modifications, may be valued less than that. Look on Ebay for "BAR belt"; "Cartridge Belt" "Browning Automatic Rifle" or other key words and see waht the belts have actually sold for. That is the best way to come up with a price. Good Luck.
