Good point, I'll bet those old Eye-talian frames saw some serious (and probably) uneven heating during construction. I guess the amount of movement when cut would be a testament to the care and skill of the builder.
I cut a ruined tt out of a Steelman frame once...zero movement of the other tubes.
So what are we gonna learn about the Unterhausen of the 70's?
