I have a shock mounting but do not know what equipment it was used on. Probably a command set or a GF-11. Could be for a dynamotor. I measures 6 inches wide, 10 inches long, and is 2 inches high. It has a number FT-241 imprinted in the aluminum. It has 4 rubber shock mounts and studs for clips to secure whatever it was designed for. Anyone need this item? J W7KSG
