GAB 50 - Marked RK

This is my best find ever got this GAB 50, GAB, EK2, CCC in silver, Estern front, KVK2  from Craigslist last year at the asked price of 1250$

But I guess nobody thought there would be any genuine items behind the extremely bad picture taken by the seller (right picture). Still owe Kengir from WAF bigtime for his help
