This is a RARE Collins MM-1 all chrome mobile mic with original Collins mic plug. This mic weighs 22 ounces. I deox'ed the contact points inside and the original matching transformer is present. The contacts and mic check continuity wise but I have no way to test as I didn't want to remove the plug so it is being sold as found, as-is. The chrome has some spots that appear to be oxidation. Did not attempt to clean other than wiping it down with some windex and soft cloth. Some of the paint on the rear label has flaked off. It is serial #5390 and says it's HI impedance. Make offer.
