Thanks P.E. It's good to know it's not vinegar syndrome anyway. I wondered whether the base was starting to deteriorate considering their age. I haven't noticed any vinegar smell around them. There's no sign of fungus and I don't think heat is very likely since they've been stored in a dry, dark and mostly cool bedroom drawer since about 1970. However I can't comment upon their early life since I wasn't around then, and it's likely they've been exposed to fumes from woodwork, clothing, toiletries and other things that have been stored alongside them.

Still, nothing lasts forever, and when I'm dead I doubt anyone will care about them anyway. :-D
Thanks for your time and effort here, it's most appreciated. :-)
