The Mossberg and Sons Model 146B was manufactured in 1954-1958.
Made from 1949-1954, the Mossberg 146B is a tubular magazine bolt action repeater. It holds 20 LR cartridges, or 30 Shorts. Very nice rifles.
Serial numbers were not required before 1968.

The "manual" for a Mossbery 146B(a) consists of a one page sheet, which is in the link below.
Two POSSIBLE sources come to mind (the 146B has been out of production for a long time now) gunpartscorp.com, which is Numrich Gun Parts, and havlinsales.com. Vic Havlin runs the Mossberg Collectors Assoc, and is pretty much THE man for anything Mossberg. And yes- ANY bolt should be checked by a smith for correct headspace when replacing a factory bolt. Having bad headspace can be dangerous on ANY firearm.
35-100 USD
Depending on condition and originality/ completeness, anywhere from $100 to $250 for a like new specimen.
Depends on condition and completeness. The rifle had 3 sights- front, rear barrel, rear receiver, and Mossberg quick detach sling swivels. If sights or swivels are missing, they are expensive to replace. Well worn specimen $100, excellent complete specimen $250-$300. Active collector interest in Mossberg 22s from this period. (Nice rifles- have 2 of them)
Gun shops, gun shows, want ads.
Do not attempt to use other than a Mossberg bolt made for that rifle.
A Mossberg 22 rifle such as the Plinkster depending on the condition is worth around $150-200.
