A winchester model 70 with the serial number you provided was made by winchester in 1938.These fine rifles are very collectable depending on the amount of original finish remaining,and in original condition.I will say that the model 70 you have left the factory without being drilled and taped for scope mounts.This was done at a later date to your rifle.You do not see many lyman alaskan scopes anymore either.You do not state what caliber or condition your rifle is in,so it will be hard to determine a accurate value for the rifle in question.I would venture to say that it can range in price from 300-1,200 dollars depending on caliber,condition of the metal and wood,and a good bore.
Based on proofhouse.com. the super .38 starting with serial number 13650 was made in 1932 so your 13xxx was made either in 1931 or 1932.
