I know nothing

I found this while geocaching.  Is it something, or nothing?

It looks like a property corner or elevation study reference point. I read that as year 1937.  It was either set by surveyor or engineer Scott Turner or was set on land then owned by Turner.  As a privately set mark, it is less to be in any geodetic data base, and I don't find it in the NGS list.

Thank you, Bill93, that's helpful.

1937 might not be a year but the Land Surveyor' state license number.    Common for LS to place their state license number on mark they set as part of a contracted survey.

I thought of that, and maybe that could have been a license number at the time it was set, but now they are much longer.  I tried the Michigan  lookup and got no match.

And the concrete looks old and weathered  enough for 1937.
