Photos in exchange for free advice

Doing chores in the basement and decided to open the safe. Pulled out my son's Longbranch 1943 which was passed on to him by his grandfather. A World War 11 vet with Radar in the Air Force when he mustered out he was issued this rifle and the other stuff pictured. They were referred to as Rangers if I am not mistaken. I would imagine there are people on here who know a lot more about military history than I do. I know you guys like photos. The rifle is pretty cherry with hardly any marks etc. I would guess it has less that a hundred rounds through it. That ammo is dated 1942. When my son got it he ran about 50 rounds of the FMJ 1942 stuff and left the brass in the bush. Not one misfire. Oh well. That was about 10 years ago. It has been parked since then. Any way I go to open the bolt and it is jammed, can't lift the bolt. I am a shotgun type and have never even shot this gun. Where do I start?
I threw in a photo of a sporterized version of an SMLE, sorry about photo quality. Bought this for my son on his 21'st from a good friend. A really nice hunting rifle.

Also what is that tool next to the short mag? It screws into the brass tube.

That brass device is used to put the oil that the tube held into place where needed.

So that would be military issue? Should this gun be listed on my son's insurance as a separate item? Does it have that much value? I am a total rookie on milsurp except for what I picked up lurking on this forum.

The safety may be in the locked bolt/safe position. Push the safety lever all the way forward.

I don't think this one rifle would necessitate a rider on your insurance. A nice nice enfield with those accessories would be in the $1k range I'd guess. Should be fine under his contents policy. (I'm not an insurance broker.)

Make sure the cocking piece is fully closed.
You might be at half ####.
With right hand depress trigger
With left hand pull back on the cocking piece and let it down fully
Then make sure the safety is fully dissengaged (all the way forward).

Ya, it looks like it is on half ####. See if you can pull the cocking piece back another notch. Then open the bolt and make sure it is not loaded.

oil the barrel.

CGN is the best. Thanks gentlemen and Merry Christmas.

I really like that sporter. It looks like a gem. Any idea who did it? Parker Hale maybe?

Sorry no idea and my buddy has since passed on. He had quit hunting as his health was failing and he sold it to me for $250. The scope is a Weaver, pretty much of a gift as he knew it was going to my son. He lived in Jasper, so probably someone in Edmonton maybe. I am on the Christmas drive right now but will check when I get home and see if there is any indication on it as to who did it. It is a gem. Lousy photo unfortunately.
