Whoa, even more info!
I was happy to have the inner "fins", but hadn't thought of keeping the hex nut innards as well!
Only thing that keeps distracting me is the "Heiland" in script and the Extension- Shutter- Extenstion on the barrel.
But, I suppose that's the way it goes...
I'm further assuming the "barrel extension" goes in w/ the middle set of two holes on top?
Thanks for all the help guys!
