CZ27 EK police rig
 

I haven't been on here in ages, but here is my latest purchase, a police CZ 27 with two matching mags and holster numbered to the pistol.

An early model 1927...Does it have the "Bohmische Waffenfabric A.G. in Prague" on the top of the slide???

Yes it does. I took it apart and the barrel also matches.

very nice one

Although these seem fairly common in my area (a friend in high school's father had one he brought back from WW II), I'm not familiar with them...What exactly makes/identifies the pistol (not the holster) as a Police CZ 27???

There is one at my LGS (minus holster); I'll be going down there later and will check it for Police markings...Whatever they are... :D

There is an eagle and a K on the trigger guard.
