DB MkIII dipstick, slightly revised to cope with today's faster roads, as used in our workshop.

Note there is a difference between the 2 types, DB2 & 2/4 is one type, DB MkIII is the other, but they don't look different at it 1st glance.

77485 for a VB series engine & 54845 for a MkIII, using the wrong one will damage your engine
