The markings (FJA - RA) indicate the stock was taken from a late Remington M1903A3, probably a year later. The rifle is not necessarily a "transitional" rifle, but should have Remington M1903 parts. I can't tell much from the pictures, except that the handguard is also a replacement and the rifle has probably been refinished. If the bore is in good condition, I would think the price is a decent one, but not a steal.
