555mm square, horizontal TT, 410mm CS, 70mm BB drop, Reynolds 631 main triangle, 525 rear triangle, TIG welded. Components including 10 speed Campag Veloce are mostly upcycled from a busted Bianchi circa 2005 except where they didn't fit. My third frame but it turned out pretty well and rides great! The paint is "Battersea" from spray.bike which is greener than it looks in the picture (and doesn't really match the bar tape).
