Hi Andrew,
The only picture showing some of those non-standard markings on T9 is well known to you, it is from the IWM collection, Catalogue number E 12348, this one:

The place of the "INSPECTED" stencil is well visible if you know what to look for. The font is typical for this stencil, something like that:

Also note that Te Aroha III has no census number stenciled on the front bumper, just a small "V" in the center, below the hole for the hand crank.
Have here a picture you may also like. Sorry but I can't recall from where it came. Some T-patrol vehicles in line, Te Aroha III in front, her name is very well visible. Behind her are T1/L4618820/Tirau II and T4/L4618942/Te Paki.
HTH
Cheers!
