Agreed, and there absolutely were M-S sporting rifles being built by Steyr post-1941. As noted above, I have one marked "Made in Germany" that was produced in 1944.

Here's more on the Clark M-S. I wonder if this one was the last 1903 ever made?

"Mannlicher Schoenauer Model 1903 Carbine. Cal. 6.5 Norm. (6.5X54). SN 25766. Beautiful little carbine with 18 inch tapered rnd bbl, ramp mounted, dovetailed front sight with German silver blade and 2-leaf express rear sight. It has dbl set triggers and the trigger bow is inlaid in heavy gold block letters “MWC”. Mounted in extra finish, very highly figured French walnut with full length stock that has raised side panels and checkered forestock with checkered pistol grip that has what appears to be a tortoise shell grip cap. Buttstock has a European cheekpiece and serrated steel buttplate with trap containing a 4-pc brass & steel cleaning rod and two other empty holes. Forestock has a sling loop with corresponding loop in the buttstock. Undoubtedly this was presented to Gen. Clark when he was the U.S. High Commissioner of Austria."
