The bottom one is an original PSO-1 4x24 which was the standard issue Dragunov scope and it still has a functioning IR detector screen and dates from the early to mid 70s.When this scope was first issued in 1964 it was the worlds most advanced sniper scope and updated versions without the IR detector (which was dropped after most opposing forces stopped using IR night vision equipment) are still very much in use with the Russians today.
I just need to get out to the range and get them both zeroed :)
