what do yo think of this PEM scope? It comes from Germany and I suppose that it was adapted to settle on a rifle K98 (the supports were welded and the space between them corresponds to a K98's mount bar. I have already seen several PEM adapted like that. What is the strangest it is the shape rounded off the central part where are fixed the thumb wheels (elevation and windage housing) . On the PEM scope this central part is squa red or hexagonal, never round. Could it be a scope of artillery and not a sniper's scope. I do not find any photo of such an optics on the RKKA's artillery pieces. No markings on the scope . Thank you for your suggestions.
