As I suspected, a Raysport (or at least ex-Raysport-shop).
Your frame's tubing is Imperial (inch-sized) as opposed to Metric (mm-sized), so your TT is 25.4mm O.D., and your ST and DT are 28.6 mm O.D. That is correct for a Raysport. Metric butted 531 tubing would take a smaller post (26.4 or 26.6) and the TT would be 26.0 mm in O.D., plus the ST and DT would be 28.0 mm O.D. The reason we asked about the tubing diameter is that, typically, a French-threaded frame would be built with Metric-diameter tubing (but not always!).
I think your seatpost is the wrong size, and that the seatlug has probably been smushed a bit around that too-small post. If it doesn't slip or look too weird, maybe do nothing about it, but you might want to consider (very carefully!) spreading the lug ears out a bit, and having the ST reamed to 27.2 mm I.D. at some point.
Cool bike!
