I forgot about the Brown & Sharpe calipers I also have............oops one of the first digitals they made......haven't used them for years hmmmmmmm wonder if the battery is still good?? update batteries dead......found an invoice in the box for repair of something back in 4/6/89 and pretty sure I bought it several years earlier ('84?) and it was pretty expensive like several hundred at the time. All in all I still like the General Tool and Instruments caliper for only forty bucks or so mainly for the fraction mode especially when quickly trying to convert thousandth or metric to fractional drill sizes in the heat of the moment.
