Correct, there are no subinspection marks visible in front of trigger housing - the numbers inside geometric shapes. Also, no visible cartouches on left side near cutoff (except for the BA-WL). It has two 'P' stamps behind the trigger - a sans serif P 7/16" high and a 1/2" diameter circle with a P inside probably serifed, but sanding makes that unsure. Maybe it's a heavy serif at bottom of vertical stalk of the circled P? The uncircled P (the most forward of the two Ps) has a rack number '109' stamped over it. I don't have access to an unsanded 03A3 stock to estimate how much wood might have been sanded away to see if cartouches may have previously been there.

If I didn't say it above, it is a pinned Remington stock with 3,475,xxx receiver and 12-44 (presumably) replacement barrel. It had bits of cosmo in the nooks and crannies when I got it. The stock was badly cracked, but thanks to candyman's prescription I repaired it; the repair worked and it shoots straight. My guess is it is an NRA or DCM 1960s rifle that somebody took apart to hurriedly clean, put back togehter without understanding the necessity of properly tightening the action screws, shot and promptly split the stock, then put it in the closet. At the wrist and also about 4" up from the buttplate somebody used a one piece dye stamp containing the word 'EASTOVER' in 3/32" letters (in other words, EASTOVER is imprinted with a single stamp, not a series of individual letters) to mark the stock. I got it from a gunshop in Massachusetts, so maybe it's a defunct military school - except that the stock is essentially undinged. Maybe some guy named Eastover did me a favor by damaging his stock and setting up a bargain buy for me many years later.

Arcieri, does your stock have similar proof marks behind the trigger guard?
