Lufkin No. 521 Surface Gage Mini Size!
This is a super nice, very rare mini Toolmaker's Universal surface gauge from the 1940's era, and comes with the 4" long spindle with both a scribe adjustable holder and another dovetail attachment to hold your dial test indicator if you wish. I tested my Interapid indicatior and it holds snug with this attachment. The gun blued mini base is only 1.5 x 2.1", and comes with a very good scriber in 98% like new condition overall. There is no wear noted, set flat on the surface plate, pins work fine. One of the nicest we have seen! Very clean, no owner's names or marks, no rust!
