Engraved with ornamental designs and locations
Built from a modified model 1853 “three band” Enfield rifle
Originally built with notch and post sights
Marksman’s sights are more recent additions, rear peep sight base has letters on left side but too worn to read.
Rifle front sight is bent (not square with barrel)
Canadian War Museum has W.P. Marston rifle (completely different style) dated from 1861.
All online examples are percussion rifles, suggesting W.P Marston Co. built rifles before the breech loading era. Dating these rifles from late 1850s to 1860s.
