Thanks all for your responses.

T-Mar:
I pulled the BB to check the tubing. Definitely has the SLX helical ridges (maybe 5 or 6, hard to count looking from above). Difficult to see in the picture. The downtube has them as well. They are only in the bottom ~half of the seat tube allowing for seat post clearance.
Also noted the Campagnolo fork ends.
And BB is Italian threading with 70-SS axle, appears to be Victory.
