Do not know anything about old vintage car lamps. This item was bought at an auction and I was informed that and on the receipt as w/o (working order) but as I ca]n't test it will sell as NON Working and for parts. On the bottom of the lamp is marked, Patented M3, 5LR. Please see photos as I don't know if missing any parts as what is on photos is what you get. In used condition with some wear on the chrome and what appears to be a crack on the face.
