Given the approximate timeframe in which this conversion was done (pre mig, tig, cnc mill, etc) my hat is off to the man who did this. The sheer volume of time put into this is deserving of respect even if it is never fired again. I have been welding for twenty years. I have a lathe, mill, mig, arc, plasma, and various other requisite tools in my shop and i would never attempt this.
I for one appreciate what you have on your hands.
So many coyotes....so little time....
