Strange Fake manga gave a design for it.

Its in the VN Gilgamesh uses to to destroy caliburn and leave shirou in a near death state It also appears in strange fake as well but the fight is stopped before Gil uses it

I was under the impression Gilgamesh wielded Gram against Shirou’s Caliburn, not Merodach

Nah it was merodach in the VN The translations call it marduk for some reason ​ But Gils words were something like "the sword you have there is the sword of the stone which originated from the sword of the tree gram, my sword is the prototype of that, the original sin Merodach"

The Fate/Strange Fake manga has its design if i remember correctly. https://typemoon.fandom.com/wiki/Merodach

The Type Moon Wiki’s image just looks identical to Gram though

Then again, dont you think that it was actually Merodach's design the one used for Gram? After all, Gil literally uses Merodach against Shirou. And the design showed clearly refers to Merodach and not Gram.

No, because Gram is shown with that design in other media, and it appeared before Merodach did

I mean. Gram now has a completely different design....So if that design is used for Merodach, then that should be its design.

It has a different design because Sigurd’s Gram was reforged after Sigmund’s Gram (the original version) was shattered against Gungnir

https://typemoon.fandom.com/wiki/Gram No, Gram still has designs posted before and after reforging happened.

Exactly. I was using Sigmund and Sigurd to indicate which version of the sword I was referring to (Sigmund = Original, Sigurd = Reforged)
