Hi everyone. Came across this rack at a junk yard yesterday off a RR P38. Paid $100, which I think is outaragous at the yard. Usually I find them for $60. Anyways, It's super heavy, steel construction I'm guessing. It has 6 metal footings with hex screws that use the factory mountings. No visible markings, If any they likely faded with age. Is this OEM? If not, who's the likely manufacturer?

Thanks for the help!
