Same situation here - grey used to be neutral, now it's a phase. Of course the transition took more time than in the UK because for almost 40 years grey wasn't really used at all (first round of harmonisation with abolition of grey neutrals in 1965, second round with grey L3 in 2003) but you can still find plenty of pre-1965 wiring. Heck, cities still have plenty of pre-WWII wiring and some pre-WWI just for the fun of it!
Every time an OAP passes away or moves you can expect to find mostly un-earthed sockets in the place (banned for new work in 1958).
