If the stocks are original to the rifle have someone who knows look it over before you fire it. Your "DF" stamp is actually a "DP" stamping on the stock ("Drill Purpose" only...ie don't shoot it, it's fu<ked)
From the receiver markings it was "FTR'd" (Factory Through repair) at the Fazerkley England "(F)" arms depot in 1948. Commonly referred to as "Faz".
From the wrist markings it was built in 1944 and I believe "M" may stand for Maltby (again in England) the wrist also has the Broad Arrow Government property mark^, and the serial number of the rifle.
As to the star, memory (which might be failing here) serves, that is from Iraq.
There will be other markings on the knox form where the barrel meets the receiver, you will want to carefully remove the fore wood and look for other DP stamps. Also look to see if all parts have the same serial number.
I'm no expert on these and someone with much more knowledge than myself will step in and correct me or further assist you. I am 100% positive on the DP stamp though. Whether the stock which is DP'd actually belongs to the gun is another matter, and even if so, why it was DP'd is another question. Everything from cracked receiver/chambers to the fact that the cadet corp needed a drill purpose rifle after the war and there is absolutely nothing wrong with the rifle was why they were DP'd.
sh1t Swan beat me to it!
The Black paint is called suncorite and was the rifles original finish.

...looking at that last pic has me wondering if someone hasn't fiddle farted with that receiver (welded a drill through spot (DP) closed and refinished the spot) have someone look at that, before you chamber one.
