1900colt,Barrel is 6 inches long
Well given the new info as to the Cylinder Length, Matching (614) Barrel Latch w/Interlock Tab & being chambered for 44/40...I'd say it's time to request a Factory Letter to confirm it's a NM#3 Frontier!! Also...to save you the trouble of finding the Link to download & print out the Request Form...I've attached the Link below!!

One thing to make sure of when you're filling out the Request Form is to specifically make mention of the Model as being a NM#3 Frontier Single Action!! You should also make sure to state it as having a 6" Barrel as that's a somewhat Uncommon Barrel Length for a NM#3 Frontier Single Action...Although "Not" so much for a Model #3 44 Dbl.-Action Frontier!! That way...if the Letter confirms the 6" Barrel Length...it should clear up the speculation as the Barrel being a Replacement or Originally Shipped in that configuration...even though it has the Dbl.-Serial Numbered Barrel with the 1880 Patent Date...Good Luck!!
