Picked up another McDermott lightbar recently. Overall it is in poor condition but all the parts are there and the arms are not bent like they usually are. The Cans needs minor bodywork and the motor is completely shot. The inside of the lift mechanism is totally rotted and it does not go up or down. I Located a new motor and piston for it online. Overall it just needs to be disassembled ,painted ,new motor and then reassembled. The history is unknown for this bar but im guessing either PAPD, NYPD or TBTA . Thanks for looking
