This is Ken (hardridden) site
HERE. He still offers the small MG Rover badge and logo along bottom line if anyone is interested.
Ken's smiley plate is made using the yellow reflective stuck on black ABS plastic, its not the best method but my rear smiley plate still looks ok after two years. Ken's front plates are made using the traditional method, the white reflective is stuck behind the clear acrylic.
I had a rear smiley plate from Demon plates, they located the British Standard Mark and their web address at top right hand corner, big no no.
