Factory-Built Variation

Several small variants exist on the different models.

The second and one of the most visible concerning the front and rear parts supporting the feet of the eagle. This part have or not what I would call "T".
They are two different types, one with this T and the other without:



Green Eagle transporter 1 st release, 2 nd release, Blue Eagle are with and without the T.
White Eagle Freighter are only with the T.

I discovered lately of the Green Eagle transporter 1 st release, 2 nd release with the presence of the T on the rear parts but not on the front parts !!!!!
It is possible with several models to recreate this hybrid model without letting trace but I think, and I am not the only one, that these models are factory-built.
