Looks like an old v1.0 interstage. 3 parachute compartments?

Could easily be some boring ERP type stuff.
So, not likely what this guy was tweeting about. (Did we ever find out?)

Musk: New design coming for Grid Fin. Will be largest titanium forging in the world. Current Grid Fin is aluminum and gets so hot it lights on fire... which isn't good for reuse.
Engineers wanted a forged beam that would save weight and eliminatethe need for many assembled components. Using a procedure developedduring work on the SST project, Wyman-Gordon produced the largestclosed-die titanium forging made anywhere in the world. The beammeasured 20 feet long by four feet across. It weighed over 4,000 pounds.Since then, over 2,000 have been produced without a rejection.
I just had 2 different people confirm to me today that SpaceX is not welding anymore new octawebs, they switched to a bolt together design. sounds pretty crazy, didnt think it would be a viable option, but also not the first time i've been proven wrong. this should make it MUUUUUUUUUUCH easier to switch between single stick cores to FH center/side boosters. very neat! wonder if we'll see the new design somewhat up close soon.
zero welding on the octaweb. the entire welding section dedicated to octaweb, robot cells etc has been dismantled and is just an assembly area now.
I haven't seen this posted here yet:
