For all CMN members who own/restore or maintain machinery I would recommend that you purchase a set of imperial and metric thread gauges along with a Zeus book, used in combination with either a suitable micrometer or digital vernier it makes identifying unknown threads easy. :thumbup: Sorry the picture quality is not the best.

Thanks as ever Fred for that little piece of history. Strange in someways when you think how the US retained imperial.
