Ok the fire selector markings are as follows..... 7 red bullet symbols for auto, one red bullet for s/a and a single white bullet crossed out and all have a thin line surrounding each, there's a marking "kal 9mmX19" on the left side of the mag well. 
  
Why does it matter? 
  
Simple really ... Should I decide to sell at any point I won't get a fair price if I type "unknown" as a brand. 
  
The previous owner did say it was a classic army but no YouTube video showed a ca bt with this type of hop, I hope it is a CA though. 
  
I have just seen on the base of the pistol grip type EG700 MP5series, does that help?
