kombi - Geez Man, I would shoot that thing as it is. Lots of those rifles have pitted barrels on the outside - one of the hazards of military use. But, if the bore is fine she should shoot OK. Check the fit of the stock to the action if there is room to play, try bedding it but only as far as the end of the chamber into the barrel channel, and free float the rest.
If you decide to scope it I would recommend a standard sporting scope mount, not a scout mount - it is just my preference. Also, that would require a new bolt handle - cutting and welding those bent bolts doesn't give you a lot of clearance - but a new bolt handle costs very little. You would also need a low safety to clear the scope - also not a major expense. Then, you have a shooter.
And the stock looks pretty darn nice, too. See how that thing feels when you touch a few off - if the recoil is ok with you then don't bother with a newer sporter stock.
One of my older 8s is a VZ-24 with a cut down military stock and brother lemme tellya that thing wallops your shoulder when you bench it - but, the stock doesn't weigh anything and doesn't wear a recoil pad so your stock should be really ok to shoot with. HTH. Mikey.
