Shell Fuzes ?

[siegfreid]

Could someone identify these for me ? I'm assuming they are base fuzes for a shell ? They both measure 1.39" long with a left hand thread diameter of 0.77" Thank you .

These are base fuzes. These were used in the base of 6 Pounder Naval explosive shells and probably others.
