i have copied your pictures and put this question to the tennessee squire association for an expert opinion!! i can tell you the stories on the bottles but barrels im not sure on !! i thought they had markings on the lids but maybe back then they wernt
yeah ive been researching and im not convinced to be honest im thinking jacks drums have 6 straps around them and there was writing burnt into the drums batch numbers and stuff!!
i may be wrong though so ill wait for an expert answer!!
