1984/5 Trek 660 Headset Question

Does anyone know what the headset specs/dimensions are?

The crown race appears to measure 26.5mm (italian), just wanted to verify I am correct.

That said, if this is italian, do you guys have any suggestions where to source italian headsets? I perused ebay and they all look ridiculously overpriced.

Tange makes a few 26.4 (1") threaded headsets as do Ritchey and Velo Orange which might cost between $15 to $60. Any bike shop with a QBP account can order them for you. And 26.4 isn't restricted to Italian even in the era that the bike was made in. Andy
