Thanks Gary,yes ,had a reread of reference books and about a year after strathearn took over Vincent left for elsewhere. Reading between the lines, it seems the new owners,not stuart Drysdale, were more interested in volume sales than perhaps Vincent was. So having said that, strathearn weights I could only say had Ysart style foundations.
But that could be said of most scottish weight manufacturers,some more than others. I'm sure they would be proud to say so. Regards Roger.
