Any opinions about this 57 Black Widow Tach now on ebay?
It registers 2 t1mes cable speed so it is distributor driven.

Would venture to guess that it one of the 4,000 rpm AC tachometers that were used in trucks and power units, has a face change to 8,000 rpm and resealed. Had several of them done years ago. Used to buy the tachs for $5-$10, send to a guage restorer I knew, spend about $75 and, voila!, you had a $500 tach
