No marking on steerer and no sign of headplate fastener holes whatsoever.
I've attached a close up of the seat binder -- cut out work is not particularly precise, matching the thoughts about the BB shell cutouts.
The frame itself is remarkably light, and I have a few 80s / 90s handbuilt steel frames that it seems comparable to (going by memory since those bikes are built up so take that with a massive grain of salt...).
