Samuel,
The RNZAF B.12s & T.13s are all scrapped.
Here is what one of my sources had to say
"The B-12 and the T-13 were operated only by 35 squadron till Dec 1977. When
the squadron converted to EW role, the B-12 and T-13 were moved around and
saw service in 16 Squadron and finally in 6 Squadron. The T-13 got phased
out in 1989, along with a host of other Canberra following the fatal
accident of F-1020 at Pune. The reason was that the C of Inquiry wrongly
deduced Canberra structural failure of the fin, when in fact the fin was
found intact in the debris."
One T.13 was used by the Test Pilot School in Bangalore and it was scrapped as well.
