Here is another, non-Coke, but Coke knock off from the same era, also picked up from the same place as the 1916 Coke. Looking at the base, it is eerily similar. Difference is , #2 instead of #4, and LGW 21 at edge of base. Both cup bottom molds, both have similar triangular bubbles in the glass, and they are the same color, although in these pics it is hard to tell.FullSizeRender-7.jpgFullSizeRender-8.jpgFullSizeRender-9.jpg
