The ugly and sloppy rear pad installation is a
feature of the Long branch No4MkI*(T) sniper. The only Long Branch snipers which I've observed which had nicely fitted rear pads which could compare to the H&H "standard" are the 90L rifles.
In my (obviously not so humble opinion) anyone comparing the fit and finish of a H&H No4T to a Long Branch No4T and deciding that the gun is a put-together because the LB is inferior in fit & finish really doesn't have any real experience with genuine Long Branch snipers.
I (like many other people obviously) put the Long Branch sniper on a pedestal above the
British
production snipers...imagine my shock when I finally obtained my first (as new in case CES by the way) Long Branch No4MkI*(T) and discovered that it was imperfect when compared to my beat up FTR'ed 1944 No4MkI(T) BSA/H&H.
My 1943 Long Branch No4MkI*(T) has the rear pad above the height of the rear rail, my 1944 Long Branch No4MkI*(T) has the rear pad BELOW the height of the rear rail (or vice versa as I'm far from home). If one searches the internet, and looks for this feature, you will observe it on non-90L rifles as being very common.
The Long Branch snipers also show 2 or more distinctive variations of shaping or machining of the cheek piece as well....I also discussed this with
Dr. Payne
some 10 years ago....
Long Branch snipers also show (at least) 2 distinct sizes of "sans serif" "T" markings, and it has been documented/reported that the early guns shipped without the "T" marking, cheek piece, lense cloth, ect.
OK since you haven't observed anyone to say it before, both JMoore's rifle (some pictures of which you seem to be mixing up with the OP's) and the OP's rifle are genuine Long Branch No4MkI*(T) rifles. I would be happy to own both, and would make a standing offer to both owners...
