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.
