For your consideration, here is a Vintage Jacobson Machine Works Advertising Drill Hole Tapering Gauge Measure, from Minneapolis, Minn.  It is 4 1/2 inches long.  The scale on on side goes from 1/ to 1/2.  The other side goes from 2 to 48, 3/4.  It has some wear and a few bends, on the pointy end.  It has a neat look to it.  Item pictured is the actual item up for sale and comes from a non-smoking household.  (431.840m-.4ob)
