I'm with you there Bartamos, why state that you have developed something new, when you're just (almost) copying originals... Or maybe perfectly copying them...:) I say almost since, no one with a 5" original lamp has come fwd to nail the fact that it had two sockets or one... All being said, I'm almost certain now it only had one.
Mike B is certainly correct stating that big bolts had the plate under the light...
