What size of number plates are you displaying on your M3W.
I have a 9"x7" motorcycle plate on the rear and a 21"x41/2" normal car on the front with the smaller 21/2" motorcycle size characters, but it looks too big. I'm thinking about a 12"x3" or similar on the front.
Having looked at the regulations, it seems that a trike with a car type body requires a front plate. It looks better with no plate, but I don't think it's legal.
Looking at some old pictures it seems most of the old trikes displayed a front plate.
