Last fall I was up in Connecticut patrolling power lines after their big snow storm and I spotted this cannon on the side of the road. I took a few pictures but didn't have time to get any measurements or look for markings. Do you know what make it is? I'm not sure where "Dale" is, but I think I saw it on a trip between Norwalk and New Milford.
I kind of thought it was a Blakely due to the trunnion band and tapering rear reinforce, but somehow the knob looks weird and I haven't seen a picture of a Blakely that looks like this. I measured my thumbnail and the bore appears to be right around 3 inches in diameter. The bore was mostly plugged up, but I couldn't see any evidence of rifling. Click on the pictures for a high resolution one.
