Wouldn't you like to have a six-pack of those coke bottles...

Note in the first picture the departure from the (previously standard) axial acoustic path, the M21 having peripheral openings in the cartridge to the element instead.

I've found two patents that I believe are embodied in this mic;

CONDENSER MICROPHONE STRUCTURE --Patent

MICROPHONE SOUND PASSAGE STRUCTURE --Patent

I find it interesting that neither patent was assigned to Altec, the first by Wm. Moreland, assigned to George Carrington, the second by George Carrington, unassigned.

Anyone know the rest of the story?
