You're right, of course. Tons of lacquer, and I wasn't about to chip it off to take a reading. That said, I find it useful because I'm the one measuring, and I measure all of them the same way. But yeah, probably not too useful to say it that way for others. Dunlop 6230 is about right. There's also a useful StewMac size that is close. In either nickel or stainless.
