I recently bought an unbranded soprano on ebay because it came with some mouthpieces which made it worthwhile. When it arrived I was surprised by how good it was - no problems with intonation and a really good tone. I assumed it was a cheap Chinese copy of a Yani but then the seller surprised me by telling me it dates back to the early 80s - he had kept in mint and oiled condition and had only recently stopped playing due to arthritis. It didn't come in its original case and has no identifying marks. One detachable straight neck, presumably there was another curved neck at some point. It looks like a copy of a Yanagisawa S880. Is it possible that it is a sax which was exported for stencilling but for some reason was not engraved by the selling shop (Rushworth's...?) in England? I didn't think that the Chinese started doing copies of Yanis etc until recently - so what could it be? If I can work out how to upload a photo I will, but it just looks like an S880.
