The Extension Searchlight Car No. 3650 O Scale was built on a cast metal depressed center chassis that is rubber-stamped in sans-serif lettering "3650 LIONEL LINES 3650" on the sides.
The GRAY searchlight housing was held in place on the car by a RED magnetic base, that could be placed beside the car as the cable was cranked out from the RED cable reel that was located in the center of the car.
