20x138B Solothurn


At a recent show i came across a german made (1942 if recall)20x138B live round. The case was made of brass and it had a pointed AP style projectile which was yellow with a white band. The owner had several of them on display along with the 20mm solothurn cannon. The round did not have a nose fuze. I cannot find anything on my reference book. Could this be a APHE-T as it was used in the antitank role? Thank you all for the help.
