I would go to Numrich Gun Parts Corp.first in my search for parts.
$350-475. depending on condition. Great gun, but plain looking.
Is it a sportsmaster .22?? If it is i can tell you.
They were made from 1940-1962, to figure out the month/year you need to look at the barrel code and look that up under the manufactured date on the Remington Society of America.
Many shotguns & .22 caliber rifles manufactured before 1968 did not have serial numbers. This would include your Rem. 512
what is the value of the Remington 1100
There should be markings on the left side of the barrel by the proofmark like K or an E and Remington has a year chart on their website
If you mean a Remington 512 X Sportsmaster, no. It is for .22 Short, Long, Long rifle cartridges. The .22 magnum is longer, larger in diameter and more powerful.
1936-1940 You could check the date code stamped on the barrel - see related links for information on the Remington Society of America.
