French WW2 Foker Wulf 190 radial engine crankcase part from BMW 801 . British called the plane the butcher . FW 190 archived a 4-1 kill ratio against allied planes mainly spitfire’s . Devastating against allied bombers . This will clean up well showing roller bearing s and a number features not sure but prop feathering drives .Really interesting piece of WW2 aviation history .Ideal for museum or collection .
