Wow ...
Just a very quick look as we're on our way out, but it has some things that I don't understand ....
As gravityfan pointed out, the same serial number for both rifle and scope?
Also ...
S5 instead of Holland & Holland marking of S51 .. typo?
I've also never seen a No.32 Mk3 scope without the red W (waterproof) and the blue B (anti bloom) paint?
