Not specifically listed in my cross-reference, but I believe you have a bolt-action .30/30 which was made by Savage and is similar to their Model 340. These would sell in nice condition for $150-$250. www.countrygunsmith.net
The Montgomery Ward Western Field model 712 is a common bolt action rifle. It doesn't have an enormous value of about $200 to $350.

Numrich gun parts
Savage made it for Montgomery Ward. It's the same as the Savage 840.
It is tough without seeing it but my first guess would be that it was made by Savage Arms and is a Savage model 340.

This firearm was maufactured by Savage as a model 840. Some parts such as the clip/ magazine were also apparently used in the savage model 340. I have ordered this magazine from numrich in n.y. for my 30-30 sb-712
100-300
In 712, it is worth 10. In 165 it is worth 100. In 381 it is worth 1.
