What do you mean by fez pieces? That is a version of the mini tan IV I created based on the ISD set.
I agree with you that the 2X4 slope would have been nice and that is how Hollander envisioned it, but I could not find them in white at the time and I will be placing them on my BL wanted list. That being said I think the addition of the red stripe in that area was a nice trade off.
You’re right it is about 2/5 the size. Your version is also about half the size of the 10198 lengthwise. Envy is already hitting me up to make him one to add to his collection.
