Union Jack, I'm afraid to say that I believe your source is mistaken. Without wishing to hijack this thread, let me explain why I think this. At Dartmouth (September 1973) we were issued with the battledress in lieu of No 5s, which weren't issued on entry but were only ordered (tailor made to fit, supposedly) closer to passing out. We were also issued with a Sea Jersey which we wore outside our shirts in the same way as the woollie pullie would be worn. At the time in the Fleet the jerseys were only uniform for the sailors and not officers, and were worn underneath No 8 shirts (the heavy blue ones); we only wore them at Dartmouth while under training. In April 1974 I flew out to Mauritius to join a ship's deployment to the Far East and the woollie pullie was introduced after this. On return to home waters for Christmas that year we undertook a RAS with an RFA and everyone on board was issued with a single woollie pullie. The entitlement was 2 but because of limited stocks we had to collect the second one from stores once we had docked in Portsmouth.
As a check that my memory is not faulty you may like to see the following:
