Hi Rick, I got it from one of the Playtime magazines that I have managed to find. Pity it's not a better photo but it's the only one I've found so far. I'm still looking for the earlier ones (Feb 1972 was the first one, I believe) as mine only start from Number 23 up until they closed (with gaps).
I will take a better photo and happily send it to you. You'll have to bear with me as I have a lot on at the moment.
As you know, I also have an old BJ manual that has some interesting photos in too as they show the Small Crown chips.
I've been meaning to send the photo of the 50p London chip (scroll mold) without inserts but not managed to get around to it, like the Playboy VSC 50p without inserts but you can get that from the guide if needed. Plus the triclub roulette without inserts but it's not cleaned up too well yet.
Hope all is well, take care and have fun.
