Hi Earl, the 'sticker' says U23M and appears on the rhs of the boot lid too. the headlights also look like VX 490 units and this gives the nose a deeper, hence, Magard look, similar to the prototype John mentioned, which had a series of five vent slots running down the side of the drivers side headlights.Whether the nose is actually deeper than the production nose, is hard to say, there's certainly not much in it, but with the narrower headlamps, it gives the effect. Also note the indicator/ sidelights and fog lights under the bumper that are behind glass/ plastic covers that mirror the headlights, and the earlier 'high top' wings, that give a visual balance to the sharper edged tail spoiler wrap around. The car also appears to have been based on a complete car taken from the production line, and therefore was probably a 'runner' and dates from June 72. Hope this helps.
Simon.
