Very old green jug

I have no clue what came in it or how long ago, but was has to be more than 50 years ago. This old green jug is marked on the bottom and I think it maybe A and H, it has a mark that looks like it, it also has the # 76 across from it and the #'s 10 and 43 with a line under the 43. In the middle are the numbers L-96409. The bottom is five inches, it is six and a half at the widest part and stands 11 and a half inches tall. This is a a very good find and in perfect condition.
