If your rifle is a Model K (not a 151K, or 640K, just Model K) THAT is going to be a challenge. That rifle was made from 1922 to 1931. I would suggest that you contact Vic Or Cheryl Havlin through their website at havlinsales, and that you check the Mossberg board at the rimfirecentral website. The Havlins perform gunsmithing and sale of parts forr Mossbergs, and operate the Mossberg Collectors Association. Good luck.
Did that thanks, I actually belong to the Mossberg Collectors Association. They do not have parts right now. This is actually the "s" version of the 22 and is missing the loading assembly I am hoping to find a parts gun so that I can restore this one I think the parts from the "k" model will work also.

There are dozens of different models of the Mossberg 22 rifle. You did not tell us which model, and we need that to give you an answer. Sorry.
Unfortunately your Model 10 Mossberg (one word) rifle was only made from 1934-1936, with the end result that parts will be VERY hard to find. Gunpartscorp has only a few parts for these on their website. havlinsales has many Mossberg .22 parts (and run the Mossberg Collector's Society) Finally, a good gunsmith can make many of the small parts that you rifle may need- but finding parts WILL be difficult. Good luck-

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. See the link.
Mossberg 22 parts are available at http://www.havlinsales.com/ and http://www.gun-parts.com/mossberg/ also at http://www.e-gunparts.com/webcontents/mossberg.htm. For the best information on Mossberg 22's go to http://www.rimfirecentral.com/forums/............. Jay1947
The mossberg model 151K was made from 1950-1951.
Made in 1976. Link at bottom of page to Mossberg .22 rifle info.
The Mossberg model 340K was made from 1958-1980.
From what I can find out it was made by Mossberg and is the same as the Mossberg model 20 and 21.
