50-125
I believe you have a Mossberg model 400 Palomino. It a .22 lever action tubular magazine walnut stock made 1959-64.. Around $100 in good condition.
The Western Auto model 117 was made by Mossberg which marketed the gun as the model 402. The 402 was produced from 1961 to 1969. The 402 is a carbine (shorter) version of the Mossberg 400 model. It is a lever action .22 cal rifle. The Mossberg manual may be easier to find than the Western Auto. You can find a schematic drawing and parts break down in "The Gun Parts Corp" catalog.
