For 127981 I see:
A 127 010 03 72, up to engine: 981 10, 20 010786 or 12, 22 002990 - I think you engine is a later engine
A 108 010 05 72, as of engine: 981 10, 20 010787 or 12, 22 002991 - you may fit here. This dipstick, they say, is available at dealers, $ 120-150 approx. I am not sure you will get a dipstick looking exactly like you wish. The 10, 20 and 12, 22 are codes for LHD, RHD, Manual and automatic.
I see another PN, A 108 010 01 72, no description.
However, for the USA you had option with PN A 127 010 04 72 (or several other part numbers), SA 10852: OIL DIPSTICK W/BREATHER FILTER & CHECK VALVE; U.S.A. This one looked like the early one or so it is shown on the drawing.
