Colt 1860 Army Long Cylinder Conversion Revolver (C12985)
Colt 1860 Army Long Cylinder Conversion Revolver (actually made from parts using new cylinders). See Study of Colt Conversions by Bruce McDowell. See pages 403-413 for a discussion and photos of a 4-screw Colt Army with exact same “conversion” as this one. McDowell suggests that approximately 60 were made. Rare Colt Conversion. Note: Grips are very good later replacements.
