Jacques, I don't know if the wheels are special, they look like standard french issue
That casting was for the last French production, before being transferred to the UK where the country code was changed and the painting hole added I believe. This modification was done after the 3 special Caravelles were issued{ Swiss, Algerie, SAS}
The one we have been searching for without success for years is the one the was produced in France after the UK production that would logically have the painting hole but with made in France and no engine cones.
BTW I just got back and your Dinky Aircraft book arrived. Great job.
You should not say your book is obsolete, and no one will order it anymore thinking at first that obsolete meant it is no longer available.
