Hank 'Oiler' Petchvarry

Hank "Oiler" Petchvarry, general go-to man and curmudgeon for most of the latter twenty years of the Victorian-Era Torchwood institute. One wonders if he's even human, because every branch seems to have someone like him, and they're all named Hank. Perhaps they're grown in a lab. History would not put it past him to have done so.
