I doubt it, CH - anyway, it's a very neat bit of work and the fella that makes it is a good folkie. I don't know if he's got a patent on it, but he deserves to get a fair reward for it.
Someone in the trade over in the States ought to get onto him and import some. They really are handy, and work far better than those expensive clumsy guitar stands, as well as being far more convenient.
