I hope the pics. will follow this, I made the barrel from a 1 1/4 - 219 Zipper barrel. 7 in. long , drilled and reamed it to .380 bore, Its threaded 1/2x 13 and the ball end was fitted and ball turned.The wood is Texas Mesquite crotch wood, 12 in. across after sawed out. A tree blowed down at my inlaws in San Antonio Tx. and believe the tree was over 150 years old and that dated back to the Alamo when I got it 20 years ago, I made the wheels also from it, The axles are brass. The sled is 9in. by 2 1/4 wide.
