Bob Streicher was famous for making manually operated single-hole
punches for use in editing or repairing paper music rolls.  He used
spring-activated center punches that he got from some company and
modified them to punch a hole rather than to make a center dimple
in material.  The replacement tips that he equipped the stock punches
with could be supplied to punch holes of various diameters.

What John Tuttle shows in his illustration looks like it might have
been one of the original center dimplers that Bob discarded when
replacing it with a hole punch of his making.
