Looks like a Model 303 Buck? I've had one for a number of years. Modded the sheepsfoot to more of a Wharncliffe much as you did. I changed the spey into more of a pen shape, but a little more pointed. The clip blade I took some of the belly off of it and took some metal off the back of it where it protrudes above the nail nick. I like the three backspring design on a three bladed knife like that. Eliminates the need to jig the blades for clearance. Good little knife. You did some nice whittling mods.
