Thank you for responding, Kuduae. It is Friedrich Wilhelm (It was in my topic header, above). About ten years ago a gentleman, now dead, found a mark on it and proclaimed it a product of F.W. Heym. I have long forgotten the details because I didn't really care. I sold it last week, and the buyer has called, requesting proof of the Heym connection. If I can't satisfy him, I will offer to buy it back (I'm sort of sorry that I let it go anyway). So I don't have it in hand. If there is no readily identifiable touchmark or trademark, I will need to get it and take some pictures. Thanks again. mike
