Panzer Beobachtungs Winkel Fernrohr (Busch)

This device was used for general observation behind an armoured plate or inside a cupola. Some observation cupolas had them installed as side optics, but the MG gunner in a cupola or behind a plate, also used them. In the main section "related" we show the armoured parts that were needed to fix the P.W.B.F. The Bunkermuseum in Zoutelande (Netherlands) has a fine collection optics and related items. This series has an optical performance of 2,5 x 19 degrees. All secimen have a prism in the head, that could rotate 180 degrees horizontally. They have reticules which could be illuminated. The headrest prevents inside light going out when there was no head before the lens.
