The original 52B was introduced in 1940 and had a 5 shot detachable magazine. A 100% rifle would go for around $2500 to whatever. They stopped production in 1978. Serial numbers ended with E 125315. Prior to 1968 they just had a number, no E prefix.
The 52B was re-issued in 1993. The re-issued rifle has a steel buttplate, forearm adjusting screw and B-type stock with small cheekpiece. They made 6,250 of them. If it is the re-issued rifle, you're looking at around $700 for a 100% gun. I don't have the serial number range for the newer rifles.
It has no E and is it's only 5 numbers ( 5 X X X X )
It has a large cheekpiece wooden stock but no scope.
It's in good condition but has no accessories. I would
say it's most likely from around the 1950s or so. I tried
to see at Gunbroker but people are asking $1,000 for
one, $2,000 for another and a third for over $3,000.
And I realize that just because people are asking
for that doesn't mean they'll get it. It's just really
hard to determine what something is worth that way.
Serial numbers for 1941 started at 50317. 1946 production started at 56080 and 1947 started at 60158, so you're between 1941 and 1947.
You're right, depending on condition you could be anywhere from $1000 on up.
I think I read something on the CMP forum where they might be getting some 52s to sell, but they're probably the newer production model, not one like your's. I'll have to go back and do a search of their old posts and see if I can find that.
The 52 (all variations) is chambered for the .22 LR. They were mostly used in NRA Smallbore rifle matches. They were "THE" rifle to use back in the 1940s through the 1970s for Smallbore matches along with the Remington 40X in .22 LR. The 40X also came in some centerfire cartridges.
