But then on the next copy I found the same engraving on both sides: 01 468884 20 1A1
I immediately thought that the engraving was just mixed up and went on to compare my other copies. The rest were all like the first one with the 1A1 on Side 1 and 1B1 on Side 2. So then I put the mixed up one onto the record player on Side 2 to see what would play. And what do I hear but the crescendoing clanking and clambering of master slave! So thanks to Tope's post I've discovered an awesome Ten mispressing that I've unknowingly had for years.

So, check your copies! Does anyone else have one?!?
