I have four - from left to right and top to bottom, they are a 6" 686-4 PowerPort, a 6" 686-0(M) w/TT & TH, a 4" 686-3 w/TT & TH and a 6" 686-3 Classic Hunter.
I've never fired the PowerPort or the Classic Hunter. I suppose I should but since they were unfired when I bought them and neither is made any longer, I just can't bring myself to do it.
