hddennis Posted July 31, 2020 Share Posted July 31, 2020 (edited) Just acquired this and would like suggestions as to what it might be and how to research it. It is a Jones Motrola type B class A tachometer. These can be found online in fitted cases with attachments to allow it to be a hand held device for measuring rpm. It normally has the ability to measure 3 different rpm ranges. My example has a single scale and is marked Maxwell Motor Company Inc. dating it to 1913 or later. I found mention of tachometer usage on Maxwell's 1914-15 factory race cars. If this is not an example of one of those racers tachometers then to my mind it has to be either a test instrument for use by the factory or a dealer used item. In 30 years of Maxwell parts chasing I've never seen another nor mention of it's use. Had it been the later 2 usages I'd have thought more than one would have survived. I welcome thoughts and suggestions. Howard Dennis Edited August 2, 2020 by hddennis (see edit history) Link to comment Share on other sites More sharing options...
Akstraw Posted August 6, 2020 Share Posted August 6, 2020 I have nothing useful to offer, but must say that it is quite an interesting find. If only objects could talk, the stories this one could tell! 1 Link to comment Share on other sites More sharing options...
