Magnum Commando Tribute VC’s
Intriguing!
I've restored a ton of those Commando fins over the years. The front and back fins are a bit closer together than the other three but it's not readily obvious looking at them. If you trim them right and add the curves around the grommet especially, it would probably be a very marketable venture. I have a couple loose ones in my stash too if you need more measurements.
