Help with ID and Technical Information Please Shell 4in Experimental.

[pkm594]

I would like some help with ID and Technical information please. The shell is a 4in Naval and maybe sound or electronic decoy. It is thought to originate from th3 40s. The squares on the background are 2cm for scale.

It appears to be fitted with a proximity fuze. What are the markings on it? Are there any markings on the projectile body?

It's a shame the images are of such a low resolution, as it makes identification hard. Anyway, I wonder if it's some form of telemetry projectile for the proofing of proximity fuzes? This because not only would it seem to be fitted with a nose proximity fuze, but some form of internal electronics assembly. Something that looks like an antenna would also seem to extend rearwards from the base plate? The only other things I can think of is some form of base-ejection emissive radar jammer (though there's not much of it within the shell), or an emitting target projectile (i.e. the internal components emits a RF signal via what would seem to be a base antenna).
