Shot one of those for a couple of years. Rod Breakage (hope spelling is correct) made them. He was from around Stillwater, OK. He made a percussion, flint and had a couple of prototype Ruger Old Army revolvers with a retro fit cylinder that was a single shot. The cylinder was flat, rotating only to load and then back to the firing position. He caught hell at the Friendship and other places from the old school guys. I shot against him a lot in OK, KS, AR, TX and a few other places. He was good.
He shot a set of the Lightning pistols like the photos and I think they were 40's. Been a few years. I shot a 40 cal and it was smooth. Some of the guys I shot with around Oklahoma has some made by Rod. He had some very good ideas. I liked my Yazels a little better because they were a little heavier.
Great photo.
