Intersting stuff - thanks for the pic of the lugs - Mine doesn't have those holes in the lugs in that picture, but it does have those identical holes in the BB lugs. Not sue what that means. How about the weight of these things? or the thickness/tolerance of the tubes?
I bought a very nice Magsitroni Senior Crankset and BB (well, nicely worn!) from a super nice guy in Sondrio Italy via ebay today. He also had a couple of Panto'd Magistroni senior headsets, unfornunately I don't want the pantography, but he has two, one with "Wilier Magistroni" and one with "Rossignoli Magistroni"...and he said he would look for one for me without the Panto - which was very nice.
Also unfortunate, that the Crankset is Magistroni with Simplex chainrings, would have been nice to be 100%, but who's counting?...
As always, keep the fedback coming, and I'll coninue on my end. I wish the guy in california tht I bought the frame from had some idea of it's origins...
