I've owned this No. 80 Mk III fuze mounted on a plinth for some years and thought I would share the markings. As can be seen from the photos it was made in India at Cossipore (Co), but also has an 'N' for Naval use. The batch number is '25' and the date is '12/10'. I've not seen any other No. 80s made in India, or marked for Naval use. Any comments appreciated! Depotman
