Used to be a company called M.O.A. that made a rolling block single-shot pistol dubbed the Maximum in or near Dayton, OH. At some point they moved out west (CO or WY if memory serves me). Always liked the looks of it, but seems they up an vanished several years ago now. Most recent post I could find anywhere on them was a guy inquiring about their value on a reddit post back in 2018. Just curious if the company still around or not.
