I do believe that many of the Wagner 1891 skillets are available from Wagner on their website only. These are old production from the last century (like 1999) and have been re-finished or processed since they were sitting around the damp, unusued foundry for several years. After these are sold there probably will not be any more new ones of the 1891 Origianls but that's only a guess. After refinishing the pans look, and are, brand new. I don't think the current owner of Wagner is the same one who provided your cracked skillet originally so you probably would not be able to get a claim or replacement.
