Service numbers 1939-45

I am trying to look up information about a man, born in 1924, who is identified in a list dated 1.4.1944 as L/Sea XXXX, with RN number P/JX 3226nn. Can anyone tell me please when this number would have been issued? I understand the P/J bit as Portsmouth, Seaman, and the X Iseem to remember means not a 12-year man so presumably includes HOs.
P = Portsmouth
J = Seamen and comms
X = new pay structure introduced early 1930s

X has nothing to do with hostilities or terms of engagement.

this prefix was used for joiners from 1934 until 1943.

Cant pin it down further as number depends upon other factors.

The prefix JX is Seaman/Tel/Bunting Tosser on a 12 year engagement (not sure about National Service or HOs) SJX signified 12 year Special Service ie 7 years active service and 5 reserve.

X therefore presumably meant entered after 1930 so pretty near all HOs should have had that. I imagine this realtes to the new pay scale that kicked off the Invergordon Mutiny or maybe related to that. However in the 50s & 60s I VERY vaguely remember a mixture of P/J and P/JX on service docs, by which time any pre-30s must have left. However it's dating the number that I would really appreciate help with. If this man was a killick in 1944 (which he definitely was) he must have come in before the end of '43.
