I had a WH20 once that had a taito badge inside the cabinet.
Don't know who put it there or why but it was there.

Daz, it seems that not ALL Taito badges were stuck to the side of every machine like someone professed before repeatedly. Lol
It seems the Taito Badge Crusader missed one when he got off the plane in Japan when he factually did EVERY Japaneese machine personally that was sent from the USA.
Playing with Match Box Ferrari cars can cause lapses in concentration.
This must be the only answer.

There shld be an inquisition immediately if a single headbox was missed & didn't get the badge.
Not doing every headbox surely must be Insanity ! ;)

Hope u are well Daz and all the best for 2016.
