Hi, I bought some old looking Hi Hats. They were described as Vintage Hi Hats with no maker's marks. What is your guess on these cymbals? Sorry the images aren't the best, but they appear to have an unlathed bell. The lathing patern on these cymbals doesn't look like Avedis Zildjian, but also doesn't look like cheap cymbals. Top Hi Hat appears to have a slightly warped edge, which, from my experience would suggest brass MIJ cymbals, but there is no JAPAN stamp. They look like they have been well used with the top Hi Hat being darker / dirtier than the bottom one.

If you recognize the look of these cymbals please.. enlighten me.

Thanks in advance.
