It appears that a lot of pruners think that the round neck wooly-pulley was the first sweater to be issued - not so. We used to get issued with a very light weight long sleeved, V-necked jumper for use in cold weather. I seem to recall that it could not be worn without a jacket and the tie was worn outside of the jumper. I found it to be very comfortable.
Also the old woolen gloves as issued to erks could not be worn unless the wearer was also wearing a raincoat or greatcoat.
