My notes indicate that the CRR was not purchased and then only in limited numbers by the Army until 1855. The Patteron Colt revolving hand gun was patented in 1836 but was not in production until 1837. The first CRR bore the Root design with the side plate mounted hammer in 1855. This does not preclude private purchase by unit commanders or indiviguals troops. My opinion is the 1830's was a transition period in weaponry from flint to cap. I myself experianced the transition from the M-14 to the M-16 I never made it to the Mattel version. During this period Viet Nam soldiers were not discouraged from purchasing their own side arms. My own .45 was manufactured in 1943 by the Singer Sewing Machine Company. It resembled a pistol but was a far better hammer. Two tied together could anchor a jon boat. Good Luck!
