Panzer Beobachtungs Winkel Fernrohr (Zeiss)
The Zeiss supplement is from an earlier date and actually made for the cupolas in the Westwall.
These persicopes had the specification 1 x 70 degrees and offered only a view dead ahead. In the main section “related” we show the armoured parts that were needed to fix this P.W.B.F.
