Nice catch, can`t be to many of those still around ! And Belgium too.
In recent months, you sometimes see blank warranty cards and booklets for sale in various places. Both seem quite new, but have a punched country code instead of a stamped one.
I dont know for sure but maybe because there were several importers back then, and some could have been specific for tax free/airport shops ?
They are not all accurate. Japanese reseller retailers will stamp a blank warranty card with their details. I’ve seen made Japanese stamped cards that emanate from Australia (i.e. with the Australia code). I’ve one here from Germany also.

Hi OF, if someone knows something about the 5021, I would be interested...
Did you ever figure it out? I have the same number?
