These parts are for older DESCO Air Hats. The old style
communications used a binding post block. The binding
posts were larger. The transceiver was mounted above the
exhaust port in a plastic cup held by a brass ring. Two sizes
of speaker were offered but the larger may not fit on very
old Air Hats due to the speaker ring location. Parts with *
indicate parts for the four wire retrofit offered for older Air
Hats.
