Okay, it's been a good minute since we don't see a DC-9-30 in 1:400 from a manufacturer other than Aeroclassics. I personally don't recognize this mold. I'm guessing it is either the Aeroclassics or Jet-X mold fitted with antennae and modern landing gear.
Given that any mold we haven't heard of in a while either doesn't exist anymore or it is owned by JC I'd say this is a resurrection of the Jet-X mold, which has not been used since 2011. What a surprise either way. I see this airplane often in Louisville, so it is nice to see a model of it.
