I have seen Fultons with the wavey lines on the sides for years, but none of the old catalogues I have show that version?!? Also, the "conventional wisdom" says the Fulton came out in 1915. However, there is a gun shown in the 1912 Schoverling, Daly & Gales catalogue that looks for all the world like a Fulton and it is called their Manhatten Arms Co. gun.?!?
