No, I've checked further and have definitive proof it is what I have it as, and that's not a Steyr.
If you can prove otherwise then I'll have a re-think, but I have to stick to saying you have not identified it.
Can't actually find any reference at all to 'Steyr' in connection with this car. Don't know what website you are looking at, but don't think anyone would seriously call any beetle "Krautwagen". That would be more a generic term used perhaps mainly by Americans to describe any Beetle, or any German car come to that!
