Krico Info

I have a gun that I can not find any info on. It is a Krico 22 semi-auto with a clip. It has a smoothbore, no riflings, two beads on top of the barrel like a shotgun. The barrel is stamped " KRIEGESKORTE + CO. STUTTGART" and " AUTOMATISCHE FLINTE DBP .a." . Also has " MADE IN GERMANY .22 L.R. SHOT-GLATT. Looks like a high grade of walnut stock. 95% mint. Any ideas on age, value, or intended use? Thanks.
