Chuck,
Please allow me to add a little bit to your post. I believe the "internal der. cable stop" was done by simply brazing two pieces of SS tubing of proper wall and OD together. Unless the part was machined out of stainless, it would rust; in Belgium or otherwise. Working with tubing is not only easier but better. I suspect Mario went this route. The rest is as you explained; a hole is cut into the chainstay and the unit brazed thru the stay. The excess is filed off flush with the tube like a top tube tunnel and there you go.
This is the only feature I have ever borrowed from Mario. I still do this on many of my frames. It's neat, clean, and pratical as a special feature. This is the one thing Mario did that was cool enough to copy. Sort of balances out the "cable housing shaver" brake cable guides.
