Thanks AmandaL. I dealt with a company called Unison Strings, who incidentally were excellent, and they ordered 2 Col Legno bows and both had a crack in the Frog!!! Hasten to add that I was put off the lack of quality control. Also as a point of interest the Dr Hider bow, that was £115 cheaper, was apparently an exact copy of the Col legno with just a different name and also made in China!!! Me thinks that they are from the same source.
I decided on the Coda Classic in the end, the design build and refinement of quality is fantastic, the company has been around for some time and most importantly the accuracy, balance and sensitivity is superb.
Very pleased
