Here is another bit of information, though I can't find any photos showing this configuration the Fw190F-8 did have the ability to mount 3/250 kg bombs (1 under each wing, 1 under center line). Oh, and further info on the case for the center line 4/50kg bombs as well:
"There were also several conversion kits developed for the F-8, which included the Fw 190 F-8/U1 long range , fitted with under wing shackles to hold two 300 L (80 US gal) fuel tanks. ETC 503 bomb racks were also fitted, allowing the Fw 190 F-8/U1 to carry one SC 250 bomb under each wing and one SC 250 bomb on the centreline." Then later is also reads "The ER4 allows to adapt the ETC 501 under the fuselage to replace the bomb (SC250 or 500) by 4 of 50 kg."
