come on John, with all the handmade work you have done on that Mersey,YOU should be able to turn out a couple of those! Make them out of wooden or resin curtain rings my friend,they are exactly the size you want.I can let you have a couple if you want,just drop me an e mail! PS were your ears burning this afternoon? Richard and I were talking about you when we met at Bude! Reply to your e mails!
cheers,
Mick
