1937 Winchester model 70 in 220 Swift - what’s it worth?

This rifle belongs to an elderly friend. I would like to help him determine the value of it. Rifle is chambered in 220 Swift, manufactured in 1937, has a Lyman Alaskan scope and a Redfield one piece scope base.

I would appreciate opinions from the Winchester folks here. Rifle is not for sale at this time. Thanks.
