Older Chicom spiker and East German ?

I passed on firing the older spiked type 56 but was wondering the 2nd rifle simple held some east german parts, as the colors were different; the gas tube being and EG finish the barrel was not. Hopefully the photo is good enough to show this... I did not have time to examine the markings or proofs; so I'm putting this riddle to the wisdom of our forum here.

Wish we had more to go on but it was the best I could do. I favor the Russian and Chinese models, and those are what I concentrated on. :smile:
