So **** photos I know…this hotel room has all yellow bulbs. Anyway, haven’t cleaned these yet but Billings & Spencer Co. Hartford Ct. And probably a B is in the triangle on the brace and 1/2 stamping..the socket is actually about 7/8 so maybe 1/2 mark is a U.S.S. sizing? Bit seems to be peened in as if previous owner wanted it to stay.
