This set has 10 pieces as is, including one large compass,  one beam compass extension, one divider, two ruling pens,  one drop bow compass with ruling pen extension, and spare parts. All parts in very good condition and working. 

note: The box is broken partially but it can be closed tightly.  The big divider has changed the color, although it doesn't affect its functionality, check the picture carefully.

A good, functional vintage set, perfect for Geometry Arts and Illumination.

Made in Germany.
