By the way it does appear to be a "vintage" spotlight. It has the early head shell with the topknot emblem. Later lamps have a smooth flat plate attached with rivets. It also has the correct/special "GM shorty" handle. This has not only a unique plastic grip but a shorter than standard spindle mechanism inside. The handle housing (the chrome part above the grip is also the early style with the wire retaining clamp. Later housings eliminated the screw on clamp.
