A new cool lamp for the collection showed up today!

This is an early version of the FUN 1 DA made by J. Lüber in 1964. It has shiny discs and there is 18 orange discs in the center raw.

A little special thing with this lamp is that every 4:th string is missing in the middle ring. It seems like this was made to get some more light out of it but I can’t figure out if it was made like this from the beginging..?
