It was made from 1950 to 1957. If you are interested in the older Mossberg firearms, get a copy of "Mossberg-More Gun for the Money" by Victor Havlin.

The Mossberg Model 151-K was made for two years only: 1950 and 1951.
Not sure what your question is. These are the successor to the Mossberg 152 rifles made in the '40s. The 352 K was made from 1957-59, value is about $150, depending on condition. The fold down forearm makes for a very steady hunting rifle. Parts are available from several sources, including havlinsales.com, and gunpartscorp.com.
Can't tell exactly- the Mossberg 385 bolt action shotgun was made from 1964-1983. After 83, it was made as the 385 K-A, and at an unknown later time, model changed to 385 K-B. In any event, a fairly recent manufacture.
Made from 1950-1963.
Since these rifles were made prior to the 1968 Gun Control Act, they do not have serial numbers, so cannot be dated to a single year. However, the Mossberg 151K was only made for 2 years- 1950 and 1951. It will be one or the other.
$85-$125, depending on condition.

The cost of a brand new Mossberg 16 gauge 190 K A is $125. A pre-owned unit usually ranges around $55 to $75 depending on its condition.
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.
