No4 Mk1 T Odd stock marking

[retiredpara]

Hi all,
New here to this forum. Have been collecting American for many years, have had a few Brit rifles in the past, but am a novice at Brit rifles. I have had a few over the years, but always appreciated them more for their low cost, and tough construction, as well as their ability to put steel on target.
To make a short story long, I came across a (T) recently. It is a legit rifle. Has the correct markings from what I have read from you very helpful folks here, as well as from my references. However, it has an odd marking on the right side of the butt, a one inch circle with "KMP", and just under that "S4", in serifed letters, approx 1/4 inch in height each. The letters are not in parentheses. In the US Army a unit S4 is the supply/logistical officer at Battalion and Brigade level. Could this be a storage mark/annotation of some sort?
The rifle is a 1945 M47C, with the Ishy screw. The pads have no broad arrows and only one punch mark each. The butt is still the S51 H&H marked butt. All other components appear original, as I can't find any rebuild marks. Serial numbers match all over, even on the magazine. Correct T and TR, as well as S and correctly marked rear sight. Scope number behind rear sight. Handguard correctly stamped with serial number. Proper gap between handguard and front sight post. Original wood cheek rest with screws that are unbuggered and quite patina'd. Rest of rifle looks original as well.
Sorry I cant post pics just yet. Technologically challenged at the moment.

Your thoughts on the KMP S4 marking? Thank you all
George

OK I’m so not a marking expert but because you said your rifle has an Ishy screw and you said the letters are contained within a circle I believe this is a Indian property mark much like the SIA under a broad arrow mark found on many post war RFI rifles. As I said I’m not an expert regarding stock markings especially those used by India.

I was told by an old Indian fellow that the Indian No4MkI T rifles could have anything on them. I to was looking for information on them and found that just about anything that could be done to keep them in service was done.

In the past year I've come across 3 other Indian snipers. Only one other besides mine had a chest. They all had the same ugly black peeling paint on the metal, the wood was roughly sanded and the 1916 leather slings were beat to hell. All of the parts were correct and all had been ftred to 1/3 triggers. All had the same markings on the butt.
Another oddity is the scope ring cap. They are flat and held on with allen style, hex head, metric screws. There isn't any counter sink cut for the original British style screws. The scope mount itself is unusual as well, there is a rod welded where the reinforcing bar was cast on the back side. Obviously mine was a replacement of Indian manufacture for a damaged unit or a rifle that was purchased without one.
It is also normal to find one with a No1 model REL scope as that's mostly what the British sold them.

Harjit also told me that other scopes were used as well as the No1 scopes were destroyed by use or just wore out. He also said that they were always repaired and had the lenses replaced as needed as long as the No1 scope remained functional mechanically. The reinforcement screw is a British approved feature and a good one to my way of thinking. The Brits used the screw themselves until the rifle could go back for ftr.

There's not much help here and a lot of the above is hearsay from Harjit and a board member here that really seems to know his stuff "Wheaty".

Wheaty kind of sits back and waits to chime in as I suspect he want you to look up as much for yourself as possible and maybe even add a bit of new information for himself. He seems to know his stuff and also seems to like sniper rifles of all types.

Thanks for the replies. I have been watching the enfield forum at Jouster for over a year, doing just that, gleaning all I can on these old Ts. I also have read all the posts here. My old pop taught me to do all I could to solve a problem before I asked for help! This rifle is a bit odd in that it shows some real wear to the stock, but has the original wood, good lands and grooves in the barrel, and still has the 0 bolt head. It definitely is not a shot out overused piece. My specialty in the Army was Infantry, enlisted, Junior NCO, then commissioned, so I am not a stranger to weapons. But that marking still has me wondering! Thanks to both of you.
