Faggin made )makes) quality products, even the "budget" models had pretty nice elements and high end construction, and since they are still in business you can even contact the "factory" which I believe is run by the daughter (Cristina?) of the originator, might help to write a bit of Italian (but have heard they are helpful with polite questions about old product):

Italian threaded for sure, not a big deal for the HS since "English/ISO/JP" will all fit adequately but you'll need an IT BB unit.
