Just for fun, we need to find a dynamotor that
we don't really need and that has the seals and
tag. Box the dyno up and send to Sigma Tek with
a letter explaining that it has been operated the
recommended 500 hours and you are sending the
unit to them for inspection. Then place bets on
whether they have any idea what a dynamotor is.
(Sigma Tek bought ARC in 1987) hehe
