7/19/21 - This is a very nice all original Colt US single action artillery model in the original full blue finish. It shows most of the finish intact with usual honest wear. It has a minty bore, the action is tight as a drum and works perfectly on all 4 clicks. Frame is DFC with other various mixed military numbers. The barrel is marked RAC under the cylinder pin. The markings are excellent as are the full, perfectly fitting original grips with script "RAC" banner cartouche on right side and "RAC" makings on bottom of both grips. The parts have mismatched numbers - typical for artillery models.
