What is the value of a Winchester Alpine Supreme 270 No P56869?

Sir, it does not sound like a Winchester, possibly the previous owner was confused by the caliber designation ".270 Win." I would guess that your rifle was manufactured by The Firearms Co. Ltd. of Bridgwater, England. They have been making the Alpine Mauser-action sporting rifle since about 1965. Rifles came with a plastic-finished wood stock in 243 Winchester, 270 Winchester, 30-06 or 308 Winchester. Rifles weighed about 7.5 pounds and had a five round magazine. Barrels were 24 inches and the sights were a hooded ramped blade and an adjustable Williams ramp. The K98k actions for Alpine rifles were originally refurbished war surplus, but later they were purchased from Belgium (FN) and Spain (Santa Barbara). cant find value
