From my great uncle, I just received a CZ Pistole Modelle 27 Kal 7.65.... s/n 32xxx. Right side of trigger guard shows a Lion standing in front of an N, and the left side is stamped with an Eagle and the letter K. Gun is in really good shape, has 2 p mod 27 mags, and the original Primosa Stallgart (?) holster. I want to learn more about this firearm.
