ok so a brief review of the wookipedia article and then a quick eyes on that model raises an issue. the figure is obviously the same size as the tie bomber ( base comparison) but accoridng to the wookipedia that ship is a whopping 29m in length ( compared to the 20m of the lambda shuttle and the 7.8m of the tie bomber)
so if they have been working closely with lucas arts for comparative scales then something doesnt match. I see the source for the size on wookipedia is Wotc and I have never been that into extended universe so I have no idea. anyone an expert in this or do you think the photo of the models is just to "represent" them
