Originally, none of them. They were produced in blue. Rifles that came back through for an arsenal rebuild in later years were Parkerized if the bluing was in poor condition.
You will have to contact Mossberg to find out.
If you want to see SOME of the MANY 22 semiautomatic rifles that were made by Mossberg, go to google, at the top of the screen select "image", and then type mossberg 152. If you are looking for an image of a particular Mossberg 22, you need to type in THAT model number. There are more than a dozen different models.
Depends on condition and completeness- many are missing some of the sights. For a specimen in very good condition, complete, around $250. Excellent target rifles.
No exact production numbers avaialble that I know of, but they would have not been extremely high- that rifle was only made for 2 yrs. (I have two of them- for a hunting grade of rifle they are VERY accurate)
Havlin Sales. They are available on their website. They carry many parts for older Mossberg rifles and shotguns. About $5.00 for the plastic peg, plus shipping.

Your rifle was made for Montgomery Ward stores by Mossberg, and is a Mossberg 346K. You can check with a gunsmith, or check the website for gunpartscorp (look under Mossberg). Havlinsales also stocks many Mossberg parts.
There is modest collector interest in Mossberg rifles from that period. Value will depend on EXACT condition, and completeness (many had rear sights removed to add scope- replacing them is pricy.) Prices for very good, complete, range from about $125-200.
Mossberg & Sons, Inc. manufactures the Maverick Model 88 shotgun. It is a budget-friendly alternative to the Mossberg 500 series, sharing many of the same parts and features.
There is a 151M, with a long 2 piece stock, made from 1946-1958, and a 151K, one piece stock with a rounded forearm (called a schnabel) made 1950-51. Do not have a listing for a 151 with no letter. Depending on condition, value is between $100-$225. They are great shooting rifles, and there IS collector interest in those models. Many are missing the rear peep sight, which is expensive to replace. Run a Google search for "epix mossberg models" for some good info and photos of the various Mossberg 22s.
Good question- not sure that anyone has an exact answer. The 46 B was made from 1938-1940, and production resumed after WW II, 1945-1946. These rifles did not have serial numbers (not required until 1968), so it is not certain that anyone has precise numbers. You may check with Mossberg- they are likely to refer you to the Mossberg Collectors Association, through havlinsales.com. Vic Havlin and his wife Cheryl run the Association, are very nice and knowledgeable folks- contact them. PS- the 46B is an excellent target rifle. I have one, it shoots better than I do.
