I contacted Aaron Draplin directly and asked him about the typeface.
He said the answer should go something like, “Draplin would not confirm or deny his involvement, creation, release schedule or design cues behind this mysterious font. That’s all you need to know. For now…”
If you're looking for something similar, how about Steelworks? It was designed based on a plaque that's just a few doors down from where I work in Winnipeg, Canada. Granted, it doesn't have that unique G that Draplin has.
