In an article in the May of 1944 American Rifleman by Walter Roper titled "The old and the new" he describes shooting a round butt .22 exactly like the K-22 but in 1910 -12. Supposedly sat for years in the factory after shooting poorly, due to a to slow twist rate of 1 in 10 inches. Anyone ever see this gun or maybe even own it. I see no mention of it in Supica & Nahas 3rd edition.
