Colt 1878 DA Revolver Exploded Views

The drawings listed below are scanned off existing factory catalogs, or existing books
These Illustrated parts Drawings are shown only to help you identify needed parts, they ARE NOT parts that are made or supplied by the host of this website

Most of these illustrations will be from factory catalogs, however some are taken from Frank de Haas's Single Shot Rifle book & are for identification only, & ARE NOT factory part numbers unless identified as such. This is important as about all obsolete parts suppliers use ONLY factory or closely associated numbers where ever possible so everyone is on the same page.

Note, for some of the older firearms, many over 100 years old, the factories never used what we now know as assembly drawings, but just views of many of the component parts & possibly randomly placed

Actual load times may take a while as these scanned pictures may be large, & depending on the speed of your computer & server

The above illustration was taken from NRA Illustrated Firearms Assembly Handbook, Volume II with the numbers changed to show actual factory part numbers that we use
