Fred wanted to make sure they didn’t slide around while being operated, so they all had very heavy bases. Some of them had nickel-plated brass bases, while others had steel bases. “Fred did not have a full set of fixtures and as a result his bugs did differ in detail, although the design was basically that of Horace Martin’s Vibroplex. Fred had a machine shop at home and made a number of bugs which he sold to his telegraph friends during the 1920s.
