I presume you are Dutch and will be able to understand the last bit as I don't!
There is also a small picture at this URL.
I am sure that my more learned colleagues in SN will provide additional information shortly!
Best wishes with your search and I am sorry that you were unable to converse with your father due to losing him at such a young age - it must have been a big shock to you at that age.
Regards,
