Pick Your Poison! buying Two Antique Poison Bottles

Here is a very nice pair of poison bottles, likely made by Eli Lilly and Co. in Indianapolis around the turn of there century. The larger one is newer because it has the squared ring (compare photos #4 and #8). Both have the word POISON embossed on one side and both are ribbed on three sides so as not to be confused with safe bottles, especially if picked up at night. The smaller bottle is featured first, measuring 2 1/4" high and showing a complicated set of marks on Its base presumably denoting the mold and buying perhaps date and manufacturer. Photo #3 I believe is the correct orientation with 68 and several number 7s but its upside down photo is also shown. The larger companion bottle is 3 5/8" tall with 67 over the letter F on its base. Both have clear natural amber color and are free of cracks and chips.
