I am pretty thrilled by this catalog, scanned and sent in by David Ross - thanks Dave!
It's Reynolds cycle tubing, featuring double-butted tubes (along with plain gauge and shaped tubes), apparently before "HM" or "531" were invented. The frame decal pictured just says "Guaranteed Built With REYNOLDS' PATENT BUTTED TUBES."
They proudly proclaim that the tubes are drawn from "the finest Swedish Steel" (!?!) They give the carbon content of the A- and B-quality plain gauge tubes, but not of the butted tubes. (I think it might be just the same as the A-quality seamless plain gauge tubes) Sounds like the manganese and other alloying elements came along later - these are just carbon steel.
Dave pegs the catalog as early 20s vintage - anyone know for sure? I have heard that HM came out in 1924, so that might be the upper limit for this one.
