Alright, let’s crack this open and see what we have:
I’m detecting at least two runners from the original High Grade Leo, and I think all the others are original to this kit.
Let’s zoom in a bit on that sticker sheet:
Apparently those big blue stickers are meant for arms, right around elbow joint. I’m disappointed that these aren’t made of color accurate plastic, but it looks like it’s due to the fact that it reuses the original Leo arms, and thus they couldn’t easily do so.
I guess the saving grace is that this is such a minor detail that you could easily leave the stickers off without really affecting the final look of the model.
