Hey guys,
I stand corrected, I just consulted my Colts Collector's Association info and sure enough, mainly above SN 200,000 they made some in 6 shot cylinders. It seems they ran them in 6 shot versions in serial number blocks.
This is why this is fun, you can learn something every day.
I've have (not had) an original five shot 1849 SN 70XXX Mfd. in 1853 that is in pristine shape, probably an "underwear drawer" gun and never fired. I bought it because the '49 is the best value of any Colt's percussion revolver and they are usually in the best shape. I also have two 1860s, one produced in 1861 and the other in 1862. The older one is a "family" gun passed down since issue.
Thanks for the education, I mean that seriously.
Regards,
Mako
