Thanks Marty, Unworthy, Sloar! Who da thunk it?! I just checked out the Columbus Max page and the Ampello on there sure does have the same downtube lettering as this one. Never heard of their shop. Apparently they and Tommasini did the exact same top tube internal cable spots and brake bridges.
Edit- They built Eddy's too?!
