This is a reproduced copy of the instruction manual for the model 333 machine. This would have been available with a variety of brands in various countries.
This machine may also have been produced with othe brand names. It was sold by Frister + Rossmann in the UK but I am not sure what they called it
It is printed on good quality paper and presented in booklet form, as in the original.
This manual is also available as a .pdf download.
