Winchester guru's

[Quack]

i have a friend that has a Winchester Model 70 Carbine 30-06 (wood stock) that was was bought by his grandmother back in ~1984. she's want's to sell it, but doesn't know what it's worth. she's thinking ~$800 it is unfired, has the box & everthing that would come with it when she bought it. the serial # start's with G172xxxx.

thanks for the help.
