Some posters may remember Nunczka - he'd been posting here for quite a while before eventually revealing how old he was - he was well into his 80s though always seemed younger.
The website he made about his early life has some fascinating war stories. I noticed he hadn't posted for a long time and given his age wondered about that and googled him (his name is on his website which is still up).
RIP Nunczka, 1925 - 2014
His own website - very worth a look: franek.webs.com
