Small number plates in the UK?

I quite fancy a small plate on the front of my 430. I have a UK independent manufacturer's vehicle with no front number plate at all. If (and it hasn't happened in 2 years and I have had one or two tugs) the law has a problem with this, I face a 30 pound fine without a licence endorsement. If, however, I display a plate that does not conform to BSI rules (absolutely no place at all to place one that does), I face up to 1000 pound fine and an endorsement. So it seems more sensible not to have one and just pay the 30 quid fine if the issue arises.

So, if I wear a front plate, it must be legal. There is an alternative small plate available for cars which are not "European Community Whole Vehicle Type Approval". I kind of like that look -- more italian if you like

Does anyone here know if the 430 fits this quote, or is displaying the alternative smaller plate for cars which don't fit the above?

Thanks,
Andrew
