This kit was at one time registered with the Voluntary Mobile Emergency Oxygen Dispensing Station Movement. Sender of this registration was to receive Identifying Insignia fo both "front and rear showing" and the kit was to be kept in their "motor vehicle" From late 50s, early 60s, or so I'm told.
It's very hard to find one of these kits with case. I know very litle about this piece.
