I have to disagree about the UK builders pricing of welded frames (fillet brazed)these were invariably cheaper than lugged or bi-laminated models: Claud Butler's cheapest frame set for many years was the Buccaneer (welded) their next frame up in the range(Cavalier) was lugged and was nearly a pound dearer. If you take one of their models in which they produced three separate versions welded (fillet brazed) lugged or bi-laminated the welded version was always the cheaper option in the Club or Sprint series. Higgins another famous builder of welded frames again the Ulralight (bronze welded) was cheaper than a lugged frame. In the Path model Fred produced two models lugged or welded, there was a whopping three pound more to pay for the lugged version of the Path. Stuart Purvis his welded frames were again a hell of a lot cheaper than his lugged frames. I am sure that in the 1952 the Holdsworth Laquelda was cheaper than most of their lugged frames think this also applied to A.S.Gillotts L'Atlantique as well. How about Hobbs of Barbican another prolific builder of welded frames all again a lot cheaper than their lugged versions. When looking in the various makers catalogues for their respective pricing policies on welded or lugged frames I compared like with like regarding tubing used and ends fitted etc. Please do not start another myth up that fillet brazed (welded) was dearer it most definitely wasn't when they were all making them.
Thats all for now. Keep those wheels spinning, in your memories if not still on the road. Be lucky Mick Butler Huntingdon UK.
