Cambridgeshire & Isle Of Ely Fire Service was born in 1965 after the fire brigades of Cambridgeshire & Isle of Ely amalgamated into 1 fire brigade. Cambridgeshire & Isle of Ely fire brigade merged the 10 fire stations of Cambridgeshire Fire Service & the 9 fire stations of Isle Of Ely Fire Service to cover an area of 846 square miles in area ( 492 miles of Cambridgeshire & 354 miles of Isle Of Ely ).
2 variations of cap badge exist for this joint fire brigade being a chrome and gilt examples during its 9 year existence. 
This original condition cap badge is in really good  used condition, the enamel centre with nice patina fixed to the standard fully pressed Home Office star & the 2 cap fixing lugs intact to the rear of the cap badge which show signs of being fitted to a cap at some point in its life, both slightly pinched out of shape. .
