Bob,
Thx. This only my humble opinion, but: i think the rifle itself is right. However, the triggerguard & bolt are Long Branch (Canadian) replacements. The bolt has had the original serial linished off & the 4637 stamped in its place to 'match' the rifle.
Also, someone has tried to achieve the same thing by allocating a serial number specifically to the mount......the 35whateveritis number on the mount is simply the serial number of the rifle that the scope & mount were originally mated to. As someone pointed out before a 41 rifle would have left the H&H factory with a Mk1 scope on it. The rifle has indeed been FTR'd but the scope/mount are simply a mismatch that someone has tried to legitimise.
It's a shame someone has tried to 'improve' what would have been an honest mismatch.
