But on the Perth site,the Academy M10 Terry reviewed shows both types of glacis plates come with the M10 duckbill.
That is a simple cut and paste error that creeped in... here is the review.

Note that the thumbnail does show the same image of the two glacis from the M-36 review I linked earlier. However, click on the thumbnail and you will see that the photograph is cropped to show only one glacis plate:

Having all the M-10, Achilles, and Jackson releases, I am certain that the only one with the alternate is the Jackson.
