Colt 22 Barrel **need help**

[jpc]

Been doing some research and the closest I can come is a pre Woodsman, but this barrel seems too short and no provision for sight. The muzzle does not appear to have been cut.
Barrel reads:


COLT'S PTFA MFG CO HARTFORD CT USA
PAT'D DEC 22,1903 AUG 27, 1918 SEPT 3, 1918

Any help will be appreciated

take care
