translation
I finally succeeded in translating this site from Dutch into English and I hope the result is not too bad. Any help in eliminating some clumsy mistakes from a non-native speaker will be welcomed so if you have any ambition to revise whatever part of the text do not hesitate to contact me. Your help will be appreciated.

This site is about backgrounds and history of products in an industrial area where further developments still take place. This site offers no product comparison or recommendation though and is primary focussed on products that are no longer manufactured. For completeness links to still existing manufacturers are included but none of them is sponsored.....yet.

My special thanks go out to my sun who took the burden to review and test this site. As compensation I included an image of his favourite rodent although he claims that it is not a rodent at all. It should be a member of the hare family 'Lagomorpha' but for me it makes little difference concerning the damage it once did to one of the masterpieces of my collection.

*) Unfortunately acknowledgements for the listed images are not always accurate. A lot of images had already been collected before the idea arose to build a site around it and also for a lot of the more recent images the author stays unknown to me. When you discover an images that you think needs to be acknowledged you can send me feedback and I will add an acknowledgement when appropriate. No, I will not pay any royalties. I rather prefer to return your image if required so.  Incorporation of articles and images from this site is permitted with proper acknowledgements.
