What first looks like a fairly standard Panzerkampfwagen IV is in fact something quite rare;a Panzerbeobachterwagen IV. This is the first and only picture as far as I know showing the turret roof configuration. The most obvious difference to a standard Pz.Kpfw.IV is the use of a Sturmgescühtz cupola with its 7 periscopes and the ability to use SF142 scissors periscope while buttoned up.A T.S.R.1 observation periscope was fitted into a mount to the left of the cupola, but is obscured by a box like item. An extra antenna base has been fitted on a plate where the ‘Nahverteidigungswaffe’ would normally be, near the turret ventilator, which itself is a later type with thicker armor. Mesh covers have been fitted to the top of the hull Schürzen while the long slim box in the left of the photo held the spare antennas.
