Hauck filed for a US patent for a Falling block single shot breech action in 1951 which was duely granted in 1956. The patent with detailed drawings is here: http://www.freepatentsonline.com/2749641.pdf
Matteson Fire Arms appear to have produced a gun using Hauck's patent, see this earlier thread: http://www.thefiringline.com/forums/...d.php?t=185901
