Anyone used Mid-West Abrasives grinding wheels?

[Technical Ted]

I found some for sale in my area. They are pink in color. All I know is: 29A60-J9-VJ 7"x1/2"x1-1/4". Made in USA.

I think they are a little older, because I can't find anything on-line and it looks like Mid-West doesn't even make wheels anymore.

Just wondering how they measure up compared to Norton. Price is good, but not if they are poor wheels.

Thanks,
Ted
