I would not expect a 513 S to be less expensive than a 513 T.Pretty much the same rifle,but a slightly more slender stock and barrel.
IIRC,the "S" model was only made for 5 to 7 years in the 50's,and production was less than 4000.
I had one.Was my rabbit rifle.I figured my son in law needed a good rifle.
Found a cigar box 513 receiver.No bolt.Had it many years.Discovered e-bay.
Found a bolt,then a military bolt handle....The a real nice CMP stock...a gunsmith estate sale as new 513T Matchmaster bbl.A Redfield 75.
Had a little sight height problem to mount a globe,discovered the Ken Viani solution,its a Weaver type bridge scope base,made to utilize the original receiver sight screw holes,plus a barrel mount target block just ahead of the front receiver ring.No drilling or tapping required if the bbl had target scope blocks.
This base also has the mounting rail for the Redfield 75 on the left rear of the base,about 3/8 in higher than the original mount for the 75.
I was also able to order a target sight block for a front globe sight that would utilize the original front sight screw holes.So now I can clamp a nice globe on the front.
To compliment it,I found a 8x Lyman All American with a p-lax adj objective that max s out at 200 yds...I assume its a rimfire scope.
Its one of those 90 % finished projects .
I'm thinking the scope may need a Lee dot or two
But,frankly,I doubt it will come close to what some of the 10-22 clones will do.
Like maybe starting with a lugged stainless threaded barrel type MOA receiver,a Volk trigger group and a Lilja bbl...
I agree,the Win 52 is in a different league..I have about a 1920 vintage here,looks like a trainer for a 1917,similar ladder rec sight.
Only Anschutz I have is a German little double set Mannlicher stocked Jr Varminter.....
