I believe mine was a rabbit, around 1975 or so when I was in my middle teens. The "handgun" was a single shot 12 gauge with the barrel shortened to around 10" and the stock cut off behind the pistol grip. My brother and I saw it in a movie and had to make one. Talk about a handful when that thing went off, you had to hold your support hand on top of the barrel to control it. The statute of limitations should be over with on that by now......eh.....
