I have this 30-06 Win 70 that per Winchester records was made in 1974. I've downloaded the Winchester Pricing Guide @ gundisgeststore but am unable to determine which variant it is. This one has the preferred 3-position safety (vs the 2-position). It's in nearly mint condition...just needs some very minor blemishes eliminated & I think that's doable. Need to determine its variant & value. Can anyone help me on this? Thank you.
