Just a quick noobie question - which turbos have an external wastegate adj like the one in the picture below ( from another thread here :wink: )

I am in the process of getting my project engine out of a '94 mk3 Golf TD - am stuck with no daylight freetime now until the weekend so can't finish & check tags - and am curious as too what turbo I have - I had thought it was a K24 - but I have been told this did not have an external adjust arm... so am now confused.
Any ideas?
Cheers
