This arrived today, a 57 year old kit in surprisingly good condition. The box is shown here actual size, much smaller than I remember them being (it's 1.32nd scale). Note the intriguing logo.
It has the original price tag from Franz Carl Weber, Zürich's biggest toy shop of SFR6.50, approximately US$1.50 in 1956. I paid SFR28, which works out today at around US$26, a good price if you like this sort of thing.
Here are some, but not all of the parts (the kit is complete).
And the instructions...
