When I look at a gun I look at it, as if I don't have any idea who made it beforehand. The things that are glaring to me about this rifle is:

1. The comb does not look quite right for a G&H, it is a tad too far forward, too high and too sharp/thin. Just not there.
2. Of all my G&H's, I have 2 G&H's that have multi leaf rear sights, a 1928 and a 1950 and both are on QUARTER RIBS, in fact it is hard for me to remember seeing more than a handful of their rifles, with this setup on Multi Leaf Rear Sights.
3. I don't believe the floorplate/trigger guard metal are G&H work, THERE IS NO CHECKERED THUMBPRINT and no G&H ADDRESS IMPRIMATUR.
4. The rear leaf sight looks aftermarket to me, not G&H WORK, NO ENGRAVED GOLD DISTANCE NUMBERS,NO SERRATED EDGES,GOLD NOTCH LINES ETC..
5.The STOCK lines ARE A LITTLE HEAVY AND FULL AS NOTED THROUGH its' LINES in the forearm and the action area, as noted.

ERGO...

1. An entirely built Virgil Howe rifle equipped with a NEW cadged G&H BARREL shortly after he left.
2.a PRE-WAR CUSTOM 1903 Stock with a mated G&H Barreled Action or a take off/orphan G&H Barrel on a shot out rifle.
3. I'VE GOT IT WRONG AND IT IS 100% G&H ...GO FIGURE!!!
ADDENDUM
Some other things I've noticed are, the Initial plate seems placed very high, almost under your hand at the pistol grip and the pistol grip has a little of that "attached stock" look, in its' shaping [the grip is too long in length, behind the bottom of the grip and it is, too closed a grip]. The forearm checkering looked a little large in its' coverage, for G&H. BTW I forgot to close last night, by saying as long as you got it at a fair price, I think you got a VERY NICE RIFLE, REGARDLESS OF ITS' PARENTAGE. GOOD LUCK! Jerry
