Update: arrrghh! The ejector rod I got off ebay is RH thread. I got the barreless gun. It is a 10-6 LH ejector rod. The center pin I got is shorter. Ebay is sho nuff "Pot Luck". You never know what you might get sometimes. The search for parts is still on. Looking for a 2" barrel while I'm at it. I'll go with whatever parts I find first. And if I end up with this 3" barrel, I have a little lathe work to do. It gets tight at 180 degrees out from where it needs to be.
