My records indicate your rifle was manufactured in
1935.
Hard to say what model it is... could be any one of a couple of different models. The sights
may not be original factory sights which would detract from its value as a "collector's" item.
Your rifle's barrel and chamber are made of modern quality steel and you need
not have any concerns about it's ability to contain the relatively low chamber pressures of the .30/30 cartridge.
Value depends on condition & model... take-down models have a somewhat higher value. In general, a 1935 Model 99 in "very good" (90% or better) condition with a barrel in excellent condition would be worth $700 ± $100. But be aware we're in an economic depression which has taken away some of your rifle's value.
If the forearm and rear stock are of truly "exceptional" quality walnut and well-marked, then add $100-$200 additional dollars to its value due to the premium wood.
Generally, your rifle's value will slowly continue to rise since they aren't makin' 'em anymore. The Savage Model 99, with it's rotary magazine, was undoubtedly the finest quality, most accurate lever action rifle ever made.
However,
actual value is what someone is willing to pay for it. Check on line at sites that sell firearms and compare what you have to the selling prices the various owners have put on their Model 99s.
I hope this helps you out...
Strength & Honor...
