longwinters,
Looking at my sources for Sako, we're going to need a lot more information than Sako.308 before we can help you out. I think a good beginning would be:
barrel length
all engraved lettering and location of that information
wood or fibreglass stock; matte or gloss finish, etc. w/ length of pull
butt plate or recoil pad, checkered?
What type forearm...semibeavertail
Sights or not and is receiver grooved for scope; sling swivals?
.308 caliber, I presume it is a type III medium action bolt w/ 3 front locking lugs and external extractor?
detachable magazine, 4-5-6 shot?
Weight of gun
Can you supply a photograph?
Sako was imported by Stoeger Industries, Wayne, NJ (formerly by Garcia Corp.)
