    It is of no value for a mechanic as the new instruments will do the calibration easier. Don’t know if it is rare. But I would be interested in it as it will go well with my other merc instuments like my thunderbolt engine analyzer and my merc-o-tronic. I don’t have that so I would buy it off you. What are you asking?
