Erma .22 conv. kit ?

Hi Ron,

Crown/R and Crown/U can be 1950-1975 DDR (East German) repair and check marks.

This probably makes this a DDR rework of a pre-war Erma-set. John Walter mentions them in his 'Luger Story' and he states they are very rare.

The Staghorn may indicate a postwar West-German proof. There may be some date letters near the proof, but it's difficult to see on the image.
