Jody, I would be surprised if the frame is Italian, even though it has an Italian bracket thread.
The fork crown was available in the UK from Ron Kiching, in his MILREMO range..I still have about ten of them left and use them from time to time to match up with Nervex Pro lugs as they go fairly well with a bit of filing and are far stronger than the Nervex pressed steel one. Check the fork section - is it the old thinner Imperial section of the Italian fatter oval? I have never seen one of these crowns on Italian oval..but they could exist.
The top-eyes on this frame and much else look fairly English. At first glance I thought it was an early MKM..as they made quite a lot of frames for the States, some of them with Italian threads. Also some were shipped to Proteusand Victor (?)
Hope that helps
