O Scale 1:48 Brooklyn & Queens Transit 8000-series Peter Witt trolley body shell. GHB has frames and interior available separately for this shell. We have one-piece 3D-printed frame/interior parts with slatted wood (OB) seats. Also available is the frame itself, with no interior. All frames are designed to use the Q-Car MT10 truck set with Brill 77E1 truck sideframes, with only simple screwdriver and wire-soldering installation. Also, all frames are designed to use the Q-Car # UB102 underbody set for Brooklyn Peter Witt cars. For trolley poles/hooks, use one each of the Q-Car (2) # B130 trolley poles and (2) # B152 roof hooks.
