What model is this grinder?

Another question for the awesome tool nerds here at GJ

I pulled this Ingersoll-Rand right-angle grinder out of the scrap pile at my local steel yard. IT has no markings other than IR in an oval. Nothing is wrong with it except a poorly designed and leaky trigger (which I will fix if I get tired of it)

If my research is correct, the IR-in-an-oval logo means that the tool was made either in the USA or China, right?

Other than that, I'm stumped. I'd love to know the model in case I ever need parts for it.

Figured it out! For posterity It's an IR 314A buffer/polisher, not a grinder
