New to me "C" block Smith-Corona

I recently picked up a C block Smith-Corona M1903A3. Remington and Smith-Corona had a serial number overlap of 3,600-4,000 rifles. It was "fixed" by stamping a "C" in front of the SC serial numbers. The photos are bad, I will have to wait for a sunny day to take more. The barrel is mark S C, ordnance bomb, 7-43, and is a four groove. The bolt is marked by a slight "X" on top and a punch mark and what looks like a "1". The stock is pinned, marked with a boxed FJA, an ordnance escutcheon and a small, unboxed, "O.G.E.K." (Ogden Arsenal, Ed Klouser). It also has the 1/2 inch circle P proof mark and four sub-inspector marks: 5 in a triangle, 10 in a circle, 8 in a square, 1 in a daimond.
