At any rate, someone like me has used the regular crank extractor and failed. The threads look messed up. I DID wonder whether they used TA threads, but when I discovered they weren't TA cranks (ARE THEY?), I thought, oh, surely Viscount wouldn't replicate a weirdo standard. I just assumed they had these made themselves.

However, this would explain why the extractor fit so loosely in the threads.

At any rate, I only have the drive-side crank. Not sure what I'll do with it.
