Heathkit SB/HW mics.

[doc]

 > Chuck Penson's books says "The release of these
 > microphones does not correspond precisely with
 > the release of the products which they were
 > associated. Almost all were released some time
 > just prior to the transmitter or transceiver they
 > seem to belong to." The following info is a summary
 > from that book:
 >
> companion to HX-10 in 1962 to 1967   HDP-21 (EV model 637)
> around intro of SB-101 in 1967  HDP-21A (EV model 638)
> couple years prior to SB-104  HDP-121 (EV model 619)
> just prior to SS-9000  HDP 242 (Astatic)
> AFTER dropping transceiver products  HDP-444 (Shure model 444)
