Well yes, every bit of the car is the teams own, even if they just bolted it on, they don't make the spark plugs in house for instance, but they would still be Williams F1 spark plugs if they are bespoke for their car.
If the gearbox casings are ally or mag, they were probably designed and finish machined in house but actually produced by a 3rd party, still be the teams case.
