Can anyone help me with ID on this fuze ?
It was made by EOC ( Elswick Ordnance Co ) and dated 1909.
It looks to be a T&P with a timer ring of 1-22 sec . The timer ring is the opposite way around to the No.80

There are very few markings on this one which is making ID difficult.

My initial thought was No.80 but the mixture of brass and alloy + the timer ring and steep angle of the nose make it doubtful.

Any info would be much appreciated.
