No. Its magazine holds 2, so in all, its a 3-shot.
$75-$125, depending on condition.
These were made by Mossberg as their Model 183K. Depending on condition, value may be $50-$125.
I can't tell you when it was made but I can tell you who made it. It's a Mossberg model 183k according to my catalogue.
About $100, depending on condition. The Mossberg bolt action shotguns are inexpensive, but the .410s seem to bring a few $$$ more.
53-56
Not AFAIK
You might see if schematics are available from Numrich Gunparts. Mossberg seems to have made more Western Field marked guns than anyone else, but there are quite a few from Stevens/Savage and a few other makers. The 150 is a Mossberg 183K
The Mossberg 410 183D B was made from 1950 to 1953.
The 1913 Stevens .410 singleshot is worth from about $75 to $150, depending on condition.
They are the same. Mossberg 500 series includes all shotguns. 500A is 12gauge. 500E is 410.
The 183D was manufactured from 1948 to the early 1970's and the 183K from the early 1950's to the mid 1980's.
I can't find a listing for the Western Field Mod 15k. The Mod 15 is a Mossberg Mod 80, the 15A is a Mossberg 83, and the 150 is a Mossberg 183k but all of these are .410 bore, not 12 ga. Mossberg did make most of the different models sold by Western Field, so by looking through the different diagrams of appropriate Mossberg shotguns you may be able to identify the correct model. With that information, GUNPARTSCORP.com or other parts warehouses may be able to supply the correct firing pin.
