Hi Mark,
I have a Dec 69 4/4 with the original windscreen. The 'Triplex' logo/script is in the top right hand corner (passenger side). I'll send you a photo. I tried one now but it was a bit dark and indistinct as the car is garaged because we are just about to be hit by the rainy/windy end of Storm Jonas.
I get one to you asap.
Paul
