Ral Partha

Ral Partha Enterprises, p.n. former Cincinatti, Ohio-based manufacturer of lead miniatures for use with tabletop wargaming and RPGs; has been in business since the 70s.
----
Addendum: Ral Partha ceased to exist after FASA closed. (FASA had bought then out a couple of years before the close, which lead some to theorize that FASA spread itself too thin). Technically, it was acquired by WizKids, but nothing has come out of it since. Iron Wind Metals owns a number of the Ral Partha rights though the sculptors or other means.
Addendum #2: There still exists a “Ral Partha Europe”, but it mostly puts out Battletech minis and doesn't seem to have much connection with the old company.
