Name & age of bayonet & scabbord w/only serial number

I bought this from a friend; they have no markings/names but do have matching serial numbers: ZP 6880.
Where is this from (I'm thinking Eastern Europe with the ZP letters for some reason)? What type of rifle was it for?
It has the most unusual wood handle - is it a regular bayonet handle?
Thanks in advance for any help.

 

Maybe @komokwa will have some insight.

I thought that "ZP" was a Czechoslovakia designation, or Poland? The handle looks like a synthetic wood-filled type handle to me.

Looks like an AK 47 mount.

Here's a similar one that's Romanian:

Poland AKM Type 1 (this is a lot older than yours, but just as a reference):

 

Thanks sabre - going to look up Czech bayonets now!

 

The bottom of the scabbard looks the same, right?
Thanks daveydempsey!
