Trying to find high-quality cover images for Gundam The Origin Collectors Edition Manga

I've been at this for hours and seem to have hit a brick wall. I've managed to find volumes 1, 5 and 7-12 but can't for the life of me seem to find 2-4 and 6. There are low-quality scans of the covers floating around everywhere, but they were printed with gold foil lettering so the physical scans are... less than good. I was able to stumble across a single cover that was hi-res though, and appears to be an original version of the art, and with a little digging I scraped up the rest that I've found. They can be seen [here](https://imgur.com/gallery/Ohip1Gc) to demonstrate the quality versus images like [this](http://st.cdjapan.co.jp/pictures/l/16/21/NEOBK-317187.jpg) where the text is very dark and hard to read.

In my search I came across [this amazon listing](https://www.amazon.co.jp/-/en/%E5%AE%89%E5%BD%A6-%E8%89%AF%E5%92%8C/dp/B00N1RMVWY/ref=sr_1_5?crid=1XN5717K6ZXQK&keywords=%E6%A9%9F%E5%8B%95%E6%88%A6%E5%A3%AB%E3%82%AC%E3%83%B3%E3%83%80%E3%83%A0+the+origin+%E6%84%9B%E8%94%B5%E7%89%88&qid=1657838337&s=books&sprefix=%E6%A9%9F%E5%8B%95%E6%88%A6%E5%A3%AB%E3%82%AC%E3%83%B3%E3%83%80%E3%83%A0+THE+ORIGIN%2Cstripbooks%2C145&sr=1-5) which has a compilation sheet of all 12 volumes in this style, but far too small to match up with the other hi-res versions I located, so I know this artwork is out there *somewhere*, but I can't for the life of me find these individual volumes. If anyone can read katakana/kanji and maybe navigate the web a little more thoroughly than I can by copy-pasting the series name into google and crawling through page after page of image search and other results and manages to turn these up, or even better quality if they exist, I would be super grateful.

I know this is a weird one, but hey, never hurts to ask!
