I think it is a Prestolite MDY-7045 starter, from Marine Power Engine c1980.
replaces CC part numbers 16.61-00044, 16.61-00050
It was replaced by a new ARCO 50160 starter, and then I had it rebuilt by Beach Generator Service in Revere MA.
See service receipt.
$250 or best offer, plus shipping (about 24 lbs)
