I did some more research this week on the 41 Long Colt and saw very little in the forum, and wanted to share it
There where 3 different case lengths in the history of the 41 Colt S.A., and 41 Long Colt D.A.
The original 41 Long Colt, or 41 Long Colt S.A. ( Single Action Revolver ) was
introduced in 1875 and was only made by Winchester. It had a case length of .767" - .768"
and a case rim diameter of .467" - .471" which made it easily confused with the later
41 Short Colt D.A. (Long Case).
I am hoping someone may have a picture of this item, I do not have a specimen
The 41 Colt D.A. ( Double-Action Revolver ) was introduced sometime between 1877
and 1880. After the introduction of the 41 Short Colt in 1884 the 41 Colt D.A. was renamed
the 41 Long Colt D.A…
The early outside lubricated cartridge had a case length of .926"-.955" until the introduction of the inside lubricated cartridge in 1896 when the case length was increased to 1.112-1.131" Both the outside lube and inside lube 41 long Colt D.A. have a case rim diameter on .427"=.436"
