Those Cough Syrup bottles are certainly great looking bottles and also the clear/flint glass one on the right of the last photo looks to be the earliest of the group.
Thanks David, the aqua Southern Cough Syurp is the hard one to get, i have only seen (2) over the years where i have seen several of the green ones, i am thinking if the lids are found in your area there is a chance some of the bottles may one day come up, i belive too that the flint glass is the oldest one of the group, according to what we have reseached Mr. Coxe was out of business after 1854, still looking for the rest of his known bottles as there are about three others that look like the Cough Syurp in colors but don't have Southern Cough Syurp on them.
