Moore and Wright Imperial Bore gauge Internal Micrometer No 903 Range = 2-12”. In nice vintage condition, has some staining/ light surface rust. Micrometer head turns smoothly and set appears to be complete. Has the 1/2” spacer to get the upper range out of each extension piece. Also has the calibration adjustment wrench that will probably be needed if you are working with very close tolerances and the extension handle for reaching into deeper holes. The micrometer head with the smallest rod starts off at 2” and can measure up to 12”. Comes in its original wood storage case and Moore & Wright paper label. See photos for additional condition info. Set includes 14 pieces plus the box.
