Looks like a Trap model to me.
I can't discern if the forearm is a semi-bevertail or not, but the forearm checkering rising only to the mid-height of the forearm indicates to me a "Trap" forearm. See page 123 of Ned Schwing's Superposed book.
If the Drop At Heel (DAH) is around 1-7/8" then it's a Trap version.
From the apparent Length Of Pull (LOP), it looks like very little wood was removed from the stock when the pad was installed....only enough to remove the slight curve, to add pad to a straight line surface. So I would expect the LOP to be approaching 15" - just GREAT.
My $0.02 cents, anyway.
