I ran across an exceptionally nice pre-WWII SA '03 that doesn't appears to be re-finished, but is mounted in an SA type-4 "S" stock in VG-EXC condition with some unusual markings. The stock is unmarked on the end-cap of the butt stock and has the numeral "53" stamped just behind trigger guard. It has the typical "circle P" in the normal location, but instead of a standard D.A.L. cartouche, it has a fairly large letter "P" without a circle were the cartouche would ordinarily be found. The serial # is in the 1434*** range and the barrel date is 7-34. It has an N.S. marked bolt (small hole) and the bore looks virtually new. The rear sight leaf is in the white, as is the "ON" face of the cut-off switch. It comes with a very nice 1944 Milsco sling and the asking price is $1,000.00. Is this a legit piece (a rebuild possibly?), and if so is that price about right? Thanks in advance for any insight anyone might have on this piece?
