Hi Guys, I have just purchased an old Fresnel light and it is big! Makes my strand vintage spots look like desk lamps. The fresnel light has no brand markings on it that I can find I think there may have once been one in the centre of the rear door, but no there is just a hole. The nuts which tighten the tilt are very large and cast brass, as is the pipe clamp. The pipe clamp has a small B&H stamped in it but this my be the maker of the clamp and not relevant to the light. I have no idea on the wattage or what globe to get as there isn't one to match. Any help greatly appreciated.
