your Savage model 99 rifle was made during the year 1930.That makes it 81 years old.
it was manufactured in 1941.
Depending on vintage, condition and caliber you might expect to pay anywhere between $300-$575 CDN. I currently own a 99C in .308 with removable magazine and have entertained cash offers of $400 CDN....
A 99 well its a classic. So it is around $45000 to $50000 that is not true its a 1000 at best
