Speaking of welded guns, the 37 Winchester's frame was a welded assembly. They actually made it two different ways, if I remember, and had patents for each. I was polishing one, back in the late 80's, and found what looked to be weld porosity along the side of the frame, where the water table stops, and back toward the hammer slot. I had to re-weld and heat treat that in order to save it. Finally, I looked into it, and their steel-built motto meant welded steel pieces.
