AP1086 Section 5X, 10H, Plessey Mk 4 connectors

I am looking into Plessey Mk 4 connectors, trying to follow their part number progression from RAF section reference numbers (5X, 5B, 10H etc) to current NSN’s

All 3 services used them, Army mainly as sections Z32, A841, A844 in the VAOS and Class Groups, 0568, A842, A844 in the RN. Then there was the joint services designation of connectors as Z numbers, before the current system of NSN’s.

Mixed in with this is the part numbers changing form CZ and 2CZ type numbers to 508/1 type numbers to LMF type numbers.

Does anyone have a copy of AP1086 Sections 5X or 10H, that can shed any light on this subject?
