Although, I am not an expert in vintage regimental steins, from research, I do believe this is authentic. Please looks at pictures. There are no cracks but there is something in the lithophane. Please look at pictures. There is normal scuff marks on the bottom of the stein. Again, I am not an expert. This stein does not have any tells of being a reproduction, no bumps in the handle, no skewed stiff soldiers, no nude lithophanes, and it does have proper oxidation of lid and finial. These were my grandparents. But I am not offering refunds, so please take a look at the pictures and offer accordingly.
