The exibited Fw 190A is actually the Fw 190 A-8/N. The letter "N" means Nachbau what is the replica in the English. The kite contains a couple of orginal parts of the Fw 190A-8 W.Nr. 682060 that indeed belonged to the A-8 block made by the Fieseler, Kassel. The orginal kite belonged to the 16./JG 3. The exibit is displayed as the A-8/R2 what is ( IMHO ) incorrect. In fact the plane external details indicate the A-8 variant with the standard wing. Let's see ...
1. the most characteristic detail for the A-8 ... the repositioned Pitot tube at the wing tip ...
2. the lengthened fuselage of 15cm what resulted in adding the metal extension to the fuselage at the wing roots and bottom of the engine cowling ...
3. the small hatch next to the fuel intake cap ...
4. the late engine compartment cooling vents and wheel solid rim ...
5. the new longer and more bulged top cover for the fuselage MG 131s ...
6. the wing armament consists of MG151/20E (long barrels).The bottom hatches with the shell ejector slots in the small bulges indicate the guns as well.
To sum up ... all the external details indicate the A-8 variant with 2xMG131 in the fuselage and 4xMG151/20E installed in the standard wing. Therefore no top blisters. But if it would be going to be the A-8 with the universal wing or the R2/R8 sub-type with the outer MK108 cannons (short barrels) the top blisters would be there and the bottom hatches were without the shell ejecting openings. These ejecting holes should be of the quite large rectangle shape made directly in the bottom of the wing skin next to the hatches.
