I agree that only Westinghouse used the 'Molded' Logo. the Tung-Sol and General Electric Brands used the 'Etched' Logo. I believe the only stipulation from Ford for their Bulb Suppliers was that the Bulbs carry the (FoMoCo) Logo at center, it was not stipulated that they be molded or etched, so the suppliers took it upon themselves to do what they felt like doing. Original Westinghouse Bulbs are extremely rare to find, IMHO. This is my experience from having hundreds of the original Bulbs over the years. I have seen postings from Bob Perkins that suggests he feels the same way I do.
Brant, are these manufactured by your company through a Supplier? or if not, who is manufacturing these, if you care to reveal that? Andrew
