Hi Gang: This is a nice old G.E. loudspeaker. case is heavy metal and measures 6-1/2" by 6-1/2". My guess is that it came from a communications console in some fire or police department from the 1950s. I'd like to get $15.00 for it plus postage. Any takers? If interested please reply by e-mail. 73, Michael, W1RC*at*verizon*dot*net
