long canvas carrier bag (Thorpe Hamlet NR1)

Green nylon canvas bag with drawstring closure at one end and a carrying strap. It's 4 foot long and 6 inches wide at the opening and 4 inches at the other end. Looks unused. I've no idea what it's for, fishing rods? trekking poles? rifle? or anything you fancy. Seems a shame to send it to landfill.
