I am going to Atlanta to pick these up this weekend. The guy that has them said that the number on the back is 6500. I have heard of and have specs for the :
6501
6502
6503
6509
6510
6511
And the 6512
But not a 6500. I know they are very early version MW's as the baskets are not black and I know they came out of Monitor 10's with peerless tweeters. Any other info would be cool but not necessarily needed I guess.

    ^^Yeah what he said :) My '79 7B's have them. And yeah apparently the earlier 6500's were the silver basket ones and later ones were painted black.

    Those obviously (want to stay out of trouble lol) have a date of 5/16/80 and 5/07/80.
