| Further comments | This 1/54 comes in a wooden box wih
the Faber-Castell logo in silver in the inside. On the box are scratched
the initals of an owner: "G.J.H.". On most proporties, this variation is a mixture of the 1st and 2nd variation. This makes sense as the date of manufacturing is in between the 2 other ones.
