Got this WW I 1917 Army pretty cheap; all original except it had a cut down .455 Mk II barrel (bore dimensions all wrong for 45 ACP.)
Here it is converted to a barrel w/shroud the way the factory should have made them pre war, (at least after the military production), the same as the 44 Military and 38/44 HD.
Factory pre war style 4" non-ribbed, tapered, and shrouded barrel. Stainless Mtn. Gun target barrel has had rib removed, fully rounded, and blued. I should have finished the barrel with a finer grit to better match the original WW I blue. Next time I have stainless blued I'll know to match the polish better. Mushroom knob replaced with proper vintage shrouded extractor rod with 'barrel' style knob.
Made a half penny front sight blade replacement (pinned into base). However the front blade is a full 1/10" wide and the rear sight notch has been opened up to target sight notch width of .124":
Should have been a simple barrel change and wished I could have found a Classic or Thunder Ranch 1917 Model barrel. But all I could acquire is a SS tapered barrel for a 45 Colt Mtn Gun:
Notice late model shrouds have the shroud bulge on the right side that extends all the way to the front. So that was another contour I had to add to match the pre war (and earlier post war) contour shown here on a pre Model 26:
I milled off the rib and milled down the integral front sight base to match the pre war integral fixed sight base:
Here is the rough milled barrel mounted on the gun:
Sometimes it takes a little work to get exactly what one likes. The only time I'm glad to find a cheap non-original model.
