Description

This record contains one fine (line) focus element. The museum tag that came with it said more specifically, "Fine (line?) focus element". It is composed of two parts: one gold piece and one silver piece. They are both circular. The gold piece is thicker, with various grooves and indentations in it. The silver piece fits onto the grooves in the gold piece. The silver piece has a hole in it (it is ring-shaped) that reveals the gold inside when placed on the gold piece.
