That's one of the unissued "Irish Contract" rifles. Some collectors never take them out of the mummy wrap -- the unopened wrap adds considerable value.
Personally, I would rather have a North American (Savage or Long Branch) Mk. 1. The fit and finish on these is better than the British-made guns.
I have one of those unwrapped Irish Contract rifles. At the local gun store where I paid what I thought was a ridiculous amount of money for my unwrapped MK2, someone had unwrapped one of the rifles and left it on the rack. The store owner was furious! That rifle was beautiful. The mummy wrap on these rifles had been opened to allow importer stamping and verification of serial numbers.
One of my MK2's
It is my opinion, owning two new Long Branch Mk1's, one Savage, and several Mk2's, is that the MK2's show better machining and fitting than the war time rifles. Of the WW2 era rifles, the Long Branch MK1's are the best, but chamber finish on mine are not as precise, along with some little details compared to the non war production MK2's. Considering a war deciding the life and death of civilizations was going on, the Canadians built very nice rifles, but they had to pay attention to arming the troops, NOW! I am sure that getting the things out the door was upper most in everyone minds. Post war click elevation rear sights are better for shooting.
This is one of the better Long Branch rear sights.
My Savage, the foreend fell off when the trigger guard was removed. It was very inaccurate in that condition , would not hold on a 8 X 11 inch sheet of paper at 100 yards. However, I bedded the action and center bedded the barrel, and the best group was two inches, but it really is a 4 MOA thing. Which is perfectly acceptable for a battle rifle, and for troops who may have had only 20 rounds of familiarization before going into combat!
The gun clubs last WW2 veteran, Sammy, had a total of 20 rounds of familiarization before landing on Iwo Jima. He had two ten round sessions at 200 yards, took the first carbine back to the armorer's to get the sights adjusted, and once his ten round string was done, they took that carbine away from him!. That also happened for the next 10 round familiarization. New carbine, got it zero's, and it was taken away. He was issued a unknown carbine on entering the invasion ship, and he told me, he had to sight the thing in while under fire!. He asked his buds to spot for him, and he knocked the rear sight with the butt of a knife, to center the point of impact!.
Sammy believed that if his Dad had not taught him how to shoot before the war, he would have been an occupant of a grave in a National Cemetery. He called the men with him "cannon fodder".
You probably know that the Savage rear sight had two settings: 300 yards and 600 yards. And that, in theory, adding a bayonet brought the zero down to 200 yards.
I added a taller front sight to get a 100 yard zero and that is good enough for me.
