It is a TPTP round, Target Practice Trace Projectile, coloured black as opposed to the Mil. green HEAT round.
The insides are identical to the real thing, but the charge area is filled with white clay to maintain weight, the piezio ignition is for the base trace charge.

Just to avoid confusion, as the 84mm Carl Gustav also had a TPTP round, the round for the 106 RCL was actually called Cartridge QF 106mm, but to avoid confusion with the American training round, which was similar to HEP and not in Australian service, it was simply called TPT Projectile .
The Australian made round having a tracer element whereas the American practice round did not.

See...our practice rounds were painted blue. And lay everywhere out there on the range until a level one clearance was done, then they were loaded into trucks for disposal. Same filler, just a plaster type thing.

Sorta Daan on the right track, bit more to see! 303 round bottom Rt for scale.

I also found this pic of when I had finished the paint resto of the markings on it.

Here is a projectile I may as well keep rolling with the bigger stuff I have collected along the way, additionaly mounted in its correct case next to my largest case (Black thing is a bug killer in the rear).

I have since aquired a better case for it.

Left is M456A2 Heat-T round, except blue for practice? The right one is a 120 mm?

[CINDERS]

Pretty much bang on with it Jim its from a Leopard 1 a HEAT Prac round for the 105 mm Royal Ordnance L7A3 L/52 rifled gun.

The Brass case next to it is not what you think its from a RAN Destroyer that was in RAN service based on a USA design. You are close Jim but not quite right.........

[browningautorifle]

I first thought it was an 88mm anti aircraft. There's one for sale hereabout right now without projectile.

Is it the 4.7 navy gun? Like this one?

[CINDERS]

Nope our last destroyers like the Perth were of an American design and had the remote controlled 5" gun;
"The 5-inch/54-calibre (Mk 45) lightweight gun is a modern naval artillery gun mount consisting of a 5-inch (127mm) L54 Mark 19 gun on the Mark 45 mount. It is designed to be used for Naval Gunfire Support and against surface targets."

Thanks for having a go Jim.
