Jack and Jill Food Warmer

Hi -- While cleaning out my mother' house, we found this Jack and Jill Food Warmer with "G.W. Co, Germany 205 " marked on the base. We haven't had any luck finding the item online nor anything about the company. We were able to find a plate with the same Jack and Jill image made by "L.G. Co., NY, Germany". I suspect that there was a merger or acquisition of one or the other, but havent been able to confirm. Does anyone have any thoughts or suggestions? Thanks!
