The original Skullhunter Owl (in pewter) was released in 2016 and has been available on and off, since then. We followed up in November 2018 with two new versions of that design. One was in bronze and another in cobalt-chrome, with each being limited to ten (10) pieces. In December 2020 we revisited those and added a fourth metal (three (3) done in nickel-chrome). The bronze variant received a green patina, with five (5) made. And finally the cobalt-chrome with updated colorization, and limited to ten (10).
