I purchased a set about 6 months ago from the States from a guy that had a set in near pefect condition. Over the years looking to buy a set I could not find any and most suggested I make up a set from a different machine but that just went against the grain for me. Therefore, if you are like me and no-one can help you here, just keep an eye out O/S and see what comes up. I will keep an eye out for you myself!
