I am sorry, it's not a front engine one (I think you mean the Whatsit, see my link). Here is the full frame photograph with Arrowbile written on the body. I take it this was Arrowbile N°1, and my puzzle showed Arrowbile N°2. It think it never was "Arrowmobile". It may have been changed, afterwards, to Aerobile, but not Aeromobile (you may mix it with the Airomobile, who was not a flying car). But I'm to lazy too check it.
The server won't let me upload the goddam picture. Those interested can check the link.
