These mistakes with one nose filled in and no noses filled in occurred throughout the 5 year period. Its very hard to say which is the rarer on these. This was simply a moulding error which could have occurred any number of times on the towhook model.
These were all simply moulding errors that occurred over the 5 years until the mould was replaced.
The only time the door was partially filled in was on the passenger side, and that was a moulding error on the red hubs Batmobile.
With the passengers door, this was a moulding problem that they quickly corrected. If you look at some Batmobiles the door line doesnt go straight up to touch the wing.
The Tin Fin "National Periodical Publication" also come with "12 spoke Whizzwheels". This "12 spoke Whizzwheels" are the same from Batmobile.
