Thanks for the link. The seller specified a sale only within USA, so unfortunately it doesn't show up in my search results. I'll have to set up a profile within USA so I don't miss out on seeing things
Is the Ebay car an Arntz? It seems to be a different shape to Dad's car and mine. Ours are both early cars, so maybe there were more changes than I realised moving towards and then onto the Butler cars.
Some things might be down to the small pics, camera angles, lighting/shadow illusions or general customisation by the owner, but;
The hood scoop is way further forward than I'd expect.
The engine seems about 5" further forward.
The rear fender shape as it flows down to the rear tail lights looks too steep.
No in-fill panels at the rear of the hood opening (ie: where the hood handles latch onto with the Arntzs)
Trans tunnel "looks" a little narrower
Front turn signals look lower (space from headlight to turn signal) and facing too far downwards
Not saying these are bad things, just that it makes me wonder if it's an early Arntz or something else. I can't see the engine bay inner panels, pedal box or front chassis rails/suspension, so I might be completely wrong. If so, it's always fun to learn!
