Police marked CZ 27

[johnbhm]

 I recently acquired this pistol from my son. We found it in a lgs some years ago along with a second high polished wartime version that he parted with while redefining his collection.At the time he told me though not as nice looking this one would be much harder to replace.Long story short I have traded and helped him in his new vision so that I could keep these in the family so to speak.So now I am trying to find out what exactly do I have.I see that it is police marked but asside from the barrel and standard cz designation's is unmarked.
   Thank's for any help,John.

Congratulations!  I came across a CZ27 a week ago at a gun show, but had to pass on it as I had recently purchased a CZ24 and the seller was a bit on the high side.

I've been following a number of CZ27s on Gunbroker.com to determine what a fair price would be.
