First post and thread to the site . . . I have an Empire giant nativity set from the mid to late 1990s that was purchased new that has the type of lamp assembly with the backplate that attaches to the mold with 2 screws and the socket with cord/plug attaches with a screw and nut. Now, for the 3 piece wisemen set which I purchased used, manufactured by General Foam, the lamp assembly has the backplate that attaches to the mold with 1 screw and the socket with cord/plug attaches via a type of bar that is on the socket which slides onto the backplate. 1.) Does anyone have any ideas as to where I can find 3 of the latter backplates and sockets/plugs? 2.) Also, any preferences as to which is better? P.S. - the largest wiseman has three apparent possible openings - top, middle, and lower; of which the middle is used on mine. 3.) Do some use the upper and lower openings with 2 bulbs instead of 1?
