Former apprentice to William Billinghurst. He made hand revolved rifles, both pill
lock and percussion, on the Miller pattern.
At least one rifle was made with a shotgun barrel as the cylinder pin. (earlier than
LeMat !) Later rifles made by Bigelow showed several changes from his earlier ones:
ignition was changed from pilllock to percussion cap, the nipples were placed in
the rear of the cylinder parallel with the bore, and the cylinder catch was moved
from the front of the cylinder to the rear.
7-shot caplock revolving rifle, sidehammer, cylinder pin was a shotgun barrel which was fired
by a separate underhammer, round patchbox
