I started to think about how the Executor just isn’t the Executor without some Avenger-class (or Imperator-class, if you insist) Star Destroyers flanking it. I remembered a small pewter Star Destroyer in a local collector shop. I checked the measurements of the Executor and sure enough, the Pewter SD was almost exactly the right scale (it’s about 1/2″ short).
Here you can see the size of the Avenger to scale. My original intent was to cast a silicone rubber mold and make a half dozen Avengers in resin to complete the fleet but I think I’ll scratch build an Avenger in closer scale. Seems like it I’m going to do it I might as well make it perfect.
