Willem Kersters (1929-1998, Belgian composer) has a good article on Dutch Wikipedia, which lists five symphonies, three concertos, smaller orchestral works, and various amounts of wind/brass, chamber, vocal, keyboard, and percussion music. His only commercially recorded work, Three Bagatelles for string orchestra, are on a CD (title and label unknown, with works by Britten, Suk, and Vermuelen) that currently has two decently priced copies on US Amazon. If you wish to find it, simply type "Kersters" in the search box on Amazon (preferably US), and it'll be the only result that comes up. I don't own the CD, though. Also, you can find his Second Symphony on YouTube. I'll try cataloguing Kersters some time in the near future. Hope this helps you, Toby :)!

Do you have any of his symphonies that can be uploaded here?
