Early Rotax lamp probably acetylene but no burner. Originally nickle plated. Good front lens and working hinge on rim. Good spade mounting bracket. Needs work but a rare lamp. Please email for more photos & dimensions. I have PayPal and will post world wide.
Slightly larger body than the pair of SD's advertised, but the lens diameter is 2.25". No lens or connector. Spade type mounting. I have PayPal and will post world wide at cost
