It looks like the unit I have is a Ham-M Series 4 made in 1966. Under the
bottom pole mount section was stamped " 4 6 0 6" which is said to mean Series
4,made in 6th week of 1966". And all this only if I am interpreting it
correctly. It'salso known as the Ham II I think.
Manufacturer was Cornell-Dubilier and according to Norm's FAQ's a Ham-M used a
single-levered control box with a meter. If anyone has a spare, I'm open to
offers.Right now I can't really test this thing and for all I know it may have
Thanks to everyone for the input. Haven't used a rotor since a kid so it was
fun tofollow this out and revisit this brand.
