I’ve got a Mercer “Mikrokator type dial gauge” and the twisted strip and glass indicator needle have broken. This gauge reads down to 0.00005″ [50 millionths] and was extremely accurate until I broken the strip etc. I’ve searched the UK for experts with this type, and all reply saying its not their remit. Anybody out there know where I can send it for repair and calibration. Photo attached. thanks Graeme.
