Bought this Jan de Reus road bike. Can someone help me with identify the headset and tubing? There are no stickers or brand names.

What does the headset nut say?
Probably Reynold’s 531.
Found [this](https://www.retrobike.co.uk/threads/jan-de-reus-frame-with-galli-needle-bearing-headset.314013/) link.
It’s a strange mix of late 1970s rear dropouts and 1980s aero internal brake routing.

You’ll never know what it is without the records of who made it. You can tell a lot by the seatpost diameter. If it’s 27.2mm you know it’s .7mm wall thickness, which means butted high quality steel, likely chromoly or Reynolds. A smaller seatpost indicates thicker tubing walls, as they all are 28.6 outside diameter. It’s got the signs of a good frame, forged dropouts, nice lugs. Once it’s painted, with no decals indicating tube mfr, then who knows? As for the headset, it’s made in Japan, looks like a Tange Levin maybe. Read the stamped letters on top.
