Steen Cannons manufactured a replica Woodruff gun for the Battle of Pilot Knob State Historic Site in southeast Missouri in 2009-2010. At the time, while the dimensions of the Woodruff tube were fairly well established, we didn't know what a Woodruff carriage looked like, so we guessed, and we guessed wrong, as we discovered when in 2013 the 1864 Helena photo [posted in this thread by Rusk County Avengers] was identified as a Woodruff. The Pilot Knob replica has been mounted on a scaled-up First Model Prairie Carriage, reproportioned to the four-foot wheels Woodruff specified in his proposal. They have recently received a new carriage based on the Helena photo, other photos from Fort D in Cape Girardeau, MO, and the remains of the only known original Woodruff carriage privately owned in southwest Missouri. It will debut at the site in late April 2024. As Steen Cannons has ceased to exist, my replica carriage, the restoration of the original carriage, and the new Pilot Knob replica carriage were all constructed by Steve Cameron of Trail Rock Ordnance.
