Floyd Calderwood (It)

Two of them, Tinker McCutcheon and Floyd Calderwood, had done jail-time. With them were Lathrop Rounds (his nickname, as obscure as the Floating Dog Hotel, was El Katook), David “Stugley” Grenier, and Eddie King—a bearded man whose spectacles were almost as fat as his gut.

It’s historical Derry troublemaker Floyd Calderwood and King’s contemporary acquaintance in the fictional Tower scene are not identified as one person.
