It looked like all three mics were the same size. Not set up like 414's or other ld mics, but clearly set up like my 451's or 460's, BUT MAJOR SIZED WINDSCREENS, MAYBE 3-3 1/2". (I just wanted to cap that part, given the exchange above
) These didn't look like shotguns, unless the had really wide windscreens.
When I first looked at it 'Decca tree' went through my mind, but given that I really don't know squat about it, it was just an intuition.
