The deployment boxes for the lunar sounder antennas are attached to the SM (parts 56a, 56b and 57a), during the EVA only the VHF antenna was deployed (part 57b). For this particular part I used Siraya fast gray ABS resin, it does not brittle. Parts were ainted with Tamiya TS-4 (German Grey) and Tamiya TS-76 Mica Silver).
