Thanks for the answers, Paul and Dick! Look forward to any more photos, for sure.
Did Hauck's single shot action (or actions, if there were several types) have any significant advantage over existing designs?
I understand that by the 1960s the original actions that could take high pressure ctgs.(Hi-wall, Borchardt, Stevens 44 1/2, etc.) were getting scarcer and more expensive, and the Ruger #1 wasn't here yet, so he was filling a small but significant (to us rifle loonies) niche market. But did his action add anything important to the design of single shot actions?
