Atlantic Airlines at CVT now operate the largest Electra fleet in the world. The company has 8 aircraft on the British register. There are also 2 ex Reeve Aleutian and 3 ex Fred Olsen Electra's at Coventry waiting to return to service or being used for spares. I believe all the Electra's on the British register are now two crew.
