10.5 cm Flak 38/39 case with APC shell. Paint may be original. Red paint on shell to indicate special driving band. Shown with 6pr and US 37mm rounds for size comparison.

Head stamps and primer markings obliterated by rust. I cant make out much of the stenciling on the side of the case either.Nice round, not to often seen. Are there any markings on the case?
