I doubt it's fake. I got it directly from Keyclack through the GB.
check the T key as well
this has been an issue with GMK for a while
I think the T key is also slightly crooked, but it's harder to tell. Z also appears to be crooked.
Is this something that affects entire runs of a keyset, or is it just a per person occurrence, or is every GMK set like this? This is my first GMK set, hence my ignorance. It seems weird if not all sets are affected unless they have multiple sets of molds.
I know it's nitpicky.
