NOTE: Sid Lethbridge 2020: It appears that the moulds for Kokomo No. 50 (and maybe other patterns) went from Kokomo to Federal in 1905. No. 50 never appeared in any D C Jenkins catalogue or wholesale assortment after 1906 but did start to appear in Federal wholesale assortments and catalogues. Federal designated the stemware as Nos. 1503 and 1603 and the table pieces as No. 50."
