My father easily matched that number along with tens of thousands of dial calipers and micrometers which he and my brother have repaired. What I learned during all these years has all been put into this repository: www.longislandindicator.com Here you will find charts of manufacturers’ specifications and spare parts lists, critical evaluations of brands and models, instructions for cleaning, servicing and calibrating indicators and hundreds of web pages of information which often exceed what manufacturers’ catalogs provide. In fact, we have had manufacturers refer to our website to learn things about their own products!</i>
