This is a shift knob for a Mazda NB Roadster with a 6-speed transmission. M10 1.25 I considered using it for another purpose, but the screw hole is quite deep, and an adapter wouldn't fit, so I'm putting it up for sale. As you can see in the photos, the shift pattern is slightly worn. There doesn't appear to be any peeling of the varnish. Thank you for your consideration.
