I just found the article I was looking for in an old "tour"-magazine:

Wolber brought this rim out in ´82 to be used with tubulars and/or (of course not at the same time) clinchers. Sizes for these were 700 x 23C - 23W, 700 x 25C - 25W and 700 x 25W sport. Tubulars recommended are: Junior butyl, Special Course, International, Club-strada and Liberty 300-24
