Exactly what confuses me. I'm sure this company isn't certified to overhaul aero engines, but the power generation version is almost identical to the 202. I wonder if they actually bought the tooling from RR. I do know this company helped test one of the VTTS' engines on their test rig - the one that had metal filings found in the sump plugs - which would imply RR don't have any equipment left.
I know that RR was overhauling marine Olympus engines for the Navy but not sure if these units are anything like the 202.
If nothing else hopefully these guys could work on non flying engines to keep the remaining ground running Vulcans taxable for years to come.
