Nice photo collection. I am suspicious of the iron whips with dragon guards (Yazi) and round nodes along the length. I see what are likely fakes of these on eBay frequently, and even from a few dealers. Genuine examples of such things do exist, but every single recent example I have seen was fake. Some of the dragon guard maces are also suspicious while others are genuine. I have been fooled by some very good copies sold by honest people. In general, the nicer it looks, the more careful you have to be.
