Apart from collecting pre-war radios I am also an active member of the Dutch Association for Rocket Research (Nederlandse Vereniging voor Raketonderzoek (NERO)). More information on the website of NERO: http://www.nerorockets.org and on my own site: http://home.planet.nl/~koste129/

Collecting beer labels (a third hobby) gets less attention these days. 21,000 Labels may be enough for the moment... I also have a small collection of old beer bottles and beer mugs.
