Not sure I should come on this board and mix with you hardened criminal types. I've lived a very sheltered life.
NB. A little birdy told me that if you happen to buy a bike with an incorrect number shown on the number plate - say an 'O' where a 'D' should be - and you (in your innocence) don't notice, then all speeding tickets you'd otherwise pick up will go astray. Moreover, the fine for (innocently) having an incorrect number is only a half-crown or summat!
Now, my question is this: What the hell is a half-crown??
