I'm not sure if these bars are a variation of the GB/Dawes Concorde or, as has been suggested, a set of bars made by a company called "CONCORDE" I've never heard of such a company (but of course I could be wrong) These bars have exactly the same engraving so I believe they must have been created using the same pantograph pattern or an exact copy. Is it possible that these pre-date the bars that have Dawes Made in England stamped upon them?
