The No. 42 Picatinny Arsenal gas turbine unit was available in 1957 only. It was made of unpainted OLIVE DRAB plastic with WHITE handrails and heat-stamped lettering and an ornamental horn on top. It had a 3-position directional unit, with magnetic couplers with tabs and head light lens installed at each end, but there was no interior lighting. There are no variations.

The window struts should be carefully examined for breaks or repairs.
