Dear Grev,
my little collection of tsuba is quite similar to yours (and I'm not ashamed to admit that I bought also some very bad fake pieces). Anyway I have learned so much, and sometimes even from fake tsuba. Otherway what's the merit to collect museum grade tsuba? Provided one can afford much money, everybody can put together a remarcable collection, but true satisfaction, for me, is finding a pearl in the mud, and grasping knowledge even from marginal objects.
Bye, Mauro
