Need Help Identifying markings

[MTN-Doozie]

I've gone online trying to find the marking meanings and am having some struggles. The serial number is saying 1918 (858393). But the front of barrel has S-A with im assuming some sort of grenade thing with 1-32 underneath it. I read that was the date as well, but thats Jan. 1932
I'm also assuming, the letter B is stamped on bottom of the stock, and also in front of trigger guard is the proof markings.
On the right side of the stock there is the numbers 0852.. i got nothing for ideas.
Also on bottom of the stock there is a 1 stamped on it. I wanna say it has something to do with refurbishing?
on bottom of the stock, in front of the front screw is what looks like an X stamped into it.
Moving to the bolt, on the back of the Safety there is an R stamped on it.
on the back of the bolt handle, there is a lot. there is a crescent shape, 1, backwards C, 1, and i wanna say 904
on underside of the bolt handle is a D stamped.
Also a B.P stamped on bottom of bolt

Any info on all this would be appreciated.

The date behind the front sight is the date the barrel was made. Apparently the rifle was rebarreled after the barrel date. The flaming bomb is an ordnance symbol. The B on is a mark indicating the rifle was reimported from a foreign country to which it was on loan.
The floorplate was pinned into place by the foreign country. The R is a mark indicating
the part was manufactured by Remington. The S A indicates manufacture by Springfield Armory. Others will surely post additional answers
and correct any misinformation I may have provided.

All I could add to Herschels info is the BP on the bolt body is Bay Products, a sub contractor to S.A.
The B and 4 digit stampings, and floor plate pinning are common signs of a Greek MAP rifle. But the bolt handle stampings are a bit puzzling to me, as the Greeks usually used the
last 4 of the serial there as well. Just a wild guess but maybe Arabic?

Seasons' Greetings!

You have a CMP Greek rifle. The "B" and "X" markings in the stock are Greek markings. The "0852" is the last 4 digits of the serial number that the Greeks fitted the stock to during overhaul. The stock, subsequently, found its way onto your rifle, perhaps at the CMP. The "B" on the floorplate is a Greek marking to indicate that the floorplate has been Blocked by pinning and is no longer removable. As Herschel pointed out, the "R" on the safety lock indicates manufacture by Remington. The markings on the back of the bolt handle are the serial number of the rifle that the Greeks installed the bolt in at one time. The "R" underneath the bolt handle indicates manufacture by Remington and the "B.P." marking on the bolt sleeve indicates manufacture by Bay Products, a WWII spare parts contractor.

Happy New Year!
