Started adapting my Graze model into a Geirail as a way to procrastinate on some of the Shiden's more complicated geometry.
I'm using the HG kit as a basis, though it diverges quite a lot from the official art, particularly in the legs. Hopefully I can work out a happy medium between the two. Thankfully a large amount of the rest of the frame is directly copied from the Graze.
Rather curiously, I've found that even if we assume the Geirail does in fact have double-jointed knees (the kit does, the art doesn't seem to), they would need to be less reinforced than the Graze - you can see the bits at the front clipping through at the moment. Likewise, the whole built-up collar behind the Graze frame's head has to be missing on the Geirail (it doesn't fit under the armour collar). Once could interpret those as the points that were improved on the later frame.
[On a related note, the Gundam wiki says:
"The Mobile Suit Gundam Iron-Blooded Orphans Mechanics & World 2 book speculated that based on the model numbers of the Geirail (EB-04) and the Graze (EB-06), Gjallarhorn had developed 4 to 5 mainstay mobile suits since the end of the Calamity War and that the organization replaced its mainstay machine approximately every 50 years." I think this is missing the fairly obvious detail that it seems odd-number EB frames are prototypes. The Schwalbe Graze is designated EB-05, for example, having been developed based on that Graze frame's prototype, and there is no EB-07 mecha currently - we leap straight to EB-08 for the initial rollout of the Reginlaze in Season 2. Ergo, we might suppose there have only been three mainline frames used since the war: EB-02, EB-04, and EB-06 (I'm assuming we're not counting the Reginlaze since it's very new and rolled out anomalously fast due to the events of Season 1).
This is not especially relevant to anything but I found it interesting.]
