And just for curiosity, am I right in assuming just the main triangle's chromoly? Is the rear triangle and fork hi ten I'm guessing?
Yes, only the three main tubes are chromium-molbydenum and since butting isn't mentioned, they are plain/straight gauge. Given that it's a Tange product, it's likely Tange #5 or the seamed equivalent.
