WW1 LEEDS PALS - GREEN EMBROIDERED CLOTH PATCH

A nice and very rare item which came in with a group of One Mans items , he having served with the Leeds Pals in the Great War , ( name to buyer ).
Rifle green wool backing with gold embroidered cap badge device and " LEEDS " underneath.
It's not a school badge or similar.
My feeling is ,a sports vest or tunic sleeve badge ?
If anyone can enlighten me I would be grateful but I've spent hours trying to find one to no avail, hence concluding it's rare.
Lovely item which has been worn and as stated, came with other Pals items from the family.
Going by the service wear my feeling is a sleeve badge ?
