Can anyone tell me if the steering pump reservoir cap in the photo is definitely from a TRW pump?

A main dealer told me the pump part no. for my vehicle is 6Q0423155AE but they werent sure if it was KOYO or TRW. the part no. on the cap is 6Q0423376, is this just the part no. of the cap itself?

the cap also actually has the letters TRW on it. I could not find any other numbers on the pump itself after removing the plastic crumbling **** and foam underneath which was saturated in water

That is from a TRW system, its exactly the same as the one fitted to my wife's 2003MY Polo - and they only were fitted with TRW steering systems at that point in production.
