I've seen conversions of the 1860 and 1861, i'm wondering if other cap and ball revolvers were commonly converted. I imagine converted 1851's were not unheard of and 1858's then as now probably only needed a cylinder change. What about dragoons or colt's .31 caliber offerings, or less common guns like the 1863 Starr single-action? What cartridges did they accept? Any pictures or history would be appreciated too.
