Trying to find original crank grinder

[Brewzer67]

Does anyone know what company this logo is from? It is on my stroker crank that Muscle Motors made back in the 90's. I'm trying to find out who used to do their welded cranks. Does anyone know? A Google search turns up nothing.

Found that online. Area code 313 is in the Detroit, MI area.

Well it says precision crankshaft grinding. Do a web search.
I was probably close by them so they didn't need to be shipped.
