here are pics of my grinder and the stand it was attached to.
Any thoughts on the era of the stand?
I8URSVT - Welcome to the GJ forum and to
The Block Grinder thread!
That 1-HP Block m-257.192190 is the wide track, late model Block.
I call it that because the arbor/shaft is longer than other flat top Blocks m-357.19xxxx.
I'd be curious what the length actually is from end to end, should you get a chance to measure it.
I'm not sure why the later models have that design, but it will allow better access for buffing/polishing.
That style stand is the first Sears branded one I've seen.
It looks very well built and sturdy.
In fact, I have a Baldor that came out of a dental lab with a stand similar.
Sorry I cannot be more help.

I believe your Block and stand qualify as Vintage Machinery, just don't post or ask question about any machine made outside of America.
Hmm, now that I think about it, the stand says Made in Taiwan. You might want to contact their moderator Brian Kachadurian, and ask before posting the stand.
My guess on the stand and Block are the mid-80s.
