I just recently came across this lightly mottled cable, which I believe is a U-671. Not an uncommon style, but what caught my attention was the incuse mark "17 PAID" on the top ear(See additional picture) The piece is in excellent shape, with no flaws that I can see. Asking $25.00 plus actual postage in the lower 48. Personal check or MO is fine. Please, no PayPal.
