Yep. i suspect someone has glued one of these reticles on my friends PVS-2 tube as it was refurbished some time ago by who knows who.

Interesting that the reticle of the PVS-2 was etched to the backside or image side of the tube. With the PVS-1/IWS and L5 reticle being placed infront of the tube, perhaps this is the better solution?
