For the moment, I don't see the Japanese connection but that does not mean too much at that point. So you are saying the Japanese were poor spellers? If you hold with Denmark, FUL could be a truncation from FULD. Very odd that the sporting weapon wears STIL in 4 places. Indeed more pondering is warranted. I would say we are thinking out loud at this point?

Kind Regards,
