Hello to The Cabe crowd. I've been riding trikes and bikes since the 1950's but this is my first post to this Forum and I am happy to see a section for tricycles. Here's a trike I've had for a number of years but never knew much about it. Riveted steel, wood grips with brass ferrules, cardboard fiber(?) seat, steel cage pedals. I don't find any markings otherwise. Can anyone shed some light on age and manufacturer? My limited research puts it maybe into the early 1900's but when did riveted steel construction give way to welded tubular design in trikes (and bikes)?
