Winchester P14 help

[M94/14]

I can't help with the disc markings.

What I see is an typical Indian issue P-14 consisting of an Winchester P-14 barrelled action installed in an Eddystone P-14 Stock. The stock is marked Eddystone by the circle I.E. stamp with broad arrow above it still visible in front of the brass disc location. Also visible is the Indian Army acceptance stamp (also a circle, with numbers and a broad arrow inside it) right beside the circled Eddystone stamp. The repaired heel and toe of the stock are typical of repairs on rifles that have been used for drill purposes. Most all of the Indian issue P-14's I've observed have had this repair. I can't fathom how many hands this rifle may have been subject to over the years, but somewhere along the way it picked up the Parker 5b or 4/47 rear sight. I would suggest a previous owner added this, and possibly was the same one who sanded and attempted a refinish on the stock.

I will add that the majority of Indian P-14's I've seen reside in Eddystone "fatboy" stocks, and most of the barreled actions are Remington's. I don't know how many Winchester rifles the Indians had, as I've never run across one, 'till now...
I won't say for sure your rifle is a "put together" or "re-militarized" sporter, but it kinda leans that way. If it has a decent bore, and stock fits properly, then enjoy it for what it is.
