Time has dulled things a little here but...Yes, I recall seeing one at Boscombe, but that could have been a pre production one for U.K. MRCA testing. Op leads were 8 pin Lemo, then 12 pin Lemo was introduced which included extra pins for NVG auto sep.
ANR was battery powered, for bagger Sea King, BBMF, SHAR, Hawk (no one claims to have seen this one) and Tucano. Later introduced on Gr7. Hawk T2 uses a later set up.
