Not sure if this is the correct section for this..... But I just wanna get a trade value from a Glock collector for an early Gen 2 17: Austrian markings, all original (black) parts, and Austrian U-shape mag. Its in "police-trade in" shape with no box or docs. I couldn't find the serial on glocktalk but I'm assuming it's 1989. Serial prefix is FZ. 2-pin frame.
