Unknown Projectiles?

[Dronic69]

Guys,

Can anyone ID these two "projectiles"?

Unfortunately I have no information on the measurements - the RHS one looks 75mm to me?

Thanks
Cheers

The one on the right is a 105mm Tank Gun M468 TP-T projectile in the shape of a HEP-T or WP-T projectile. It is missing the tracer on the base. The cartridge assembly is designated M467 for the M68 Tank Gun. The projectile ID info is stamped on the body just above the top rotating band and can be seen in your photo.

The piece on the left is the windscreen from a 5 inch 38 cal navy AP projectile. This windscreen would have colored dye inside, different color for each ship. When the shells impact, water goes through holes under the copper nose cone and forces the dye out through the 4 copper plugs that are spaced radially around this piece, near the bottom.

Thanks Hazord - I was also wondering what those copper circular discs were for....so if each ship had separate colour dyes, then I gather this was for training /practice /war games?

Cheers

Yes, so multiple ships shooting at the same target could have their hits recognized.

But this feature was also useful in real action, otherwise one ship could be correcting for another ships' fall of shot.
