@ plecostomus - The correct cat# for this is 6338 771 for record 1 label - 6338 772 for record 2 label. The back cover shows 6672 015 CE. Here on 45worlds we use the cat # as shown on the record labels. Could the first number on yours be a six instead of a nine?.
Just bought a copy of this off of Ebay, the records themselves have the usual catalogue number of 9338 771, but the sleeve has the cat. no. of 6672 015 CE. It's printed in England by Howard Printers (Slough) Ltd. I'm assuming the records and sleeve have been matched up at some point but does anyone know when the sleeve was made?
