Ok, guys I got this new info on the Fw-190 at Joburg Museum thanks to delcyros who translated it for me here it is. Thanks again mate.
"These two pictures show a Focke Wulf Fw 190/A6 from III./JG 11 (W.Nr. 550214) of the South African Military Museum Johannesburg. This plane was manufactured mid 1943 at AGO plant (near) Oschersleben and modified as experimantal plane for the so called "Neptun-Liliput" device.
This special device was used for rangefinding and timing to fire 21cm rockets into bomber streams. A line of dipols on one wing was used as emitter while those of the other wing were receivers. The Neptun - Liliput (devce) coworked with the Elfe EG 3 which automaticly set the range for proper firing of the rockets and detonating of them in (proximity to) the bombers.
Following the modification to Fw-190A6/R8* the dipols should have been removed because of the higher aerodynamic drag (which) would negatively effect dogfighting abilities.
After wars end this particular plane was captured in Denmark. Following extensive analysis by the british it was send to South Africa as a present.
In this museum are also on display a two seater Me-262 B1a/U1 -nightfighter-(W.Nr.110305), a Bf-109F2/Trop of the JG 27 captured in North Africa (W.Nr.31010), a Bf-109 E3 (emergancy landing at BoB) and a flight ready Fieseler Storch Fi-156 C7 (W.Nr.475099).
*The subtype R8 for fw-190 are with two underwing gondolas 30 mm MK 108. Extra to those powerful (spelled:mighty) weapons the R8 also carried two 20 mm MG 151/20 in the wingroots and two 7.92 mm MG17 firing through the propeller arc."
