With a chrome finish and the “latest” spring-clip cord hookup, this machine was considered modern in its day.

From a 1940’s Jensen flyer, “This is no doubt the finest tattooing machine on the market today at this price.  This machine is made of the finest material, frame is made of bronze casting nicely chrome plated.  It comes fully adjusted.  They are all equipped with the latest hookup for using a spring-clip cord.  They have pure silver contacts.  All of my machines are set to run on dry cell batteries or direct current from a motor generator.  The price is $12.00 each.  Either outlining or shading.”
