Rocket Head ? Canadian marked Identification

I have been asked what this is. To me it looks
like a solid rocket head ? The marking indicates
Canadian issue of a more modern nature.

That is really interesting. Hope someone here has more info on it and possibly some photos of the complete rocket.

PS: I just put it together after so many years, but one of my favorite torpedo artifacts was purchased from you 15+ years ago. LOL
 
Has a similarity to the 20pdr AP penetrator, carried in the sabot. Maybe look in that direction?
 
Yep I agee with Kahu1 - 20pdr or maybe 17pdr core from a APDS

I had 20pdr core with the base petal at one stage - this is the only photo of it.

With that style of mark on it, it will be a 20 not 17pr., too modern.
Thanks to all, now the price will double no doubt from the absurd to the ridiculous !
 
It's very close to the sub-projectile of the Mk. 3 DS practice, but different in a couple of ways.

The first is that tracer or tracer housing is screwed into a recess in the base of the sub-projectile, whereas in the Mk. 3 the tracer is housed in an extension of the base of the sub-projectile as seen in the image (plate) posted by kahul1 which is probably taken from page the publication 'Regulations For Army Ordnance Services - Volume 4 - Ammunition - Pamphlet 8 - QF Fixed Ammunition - Part 9 - Cartridge QF 20-pr (1957)'.

Another difference, though this just might not be shown in the plate, is the knurled of the bottom edge of the sub-projectile. This is present so that on firing the setback forces push the ridges into the softer aluminium alloy sabot pot. This results in a good mating between the two and insuring the transfer of torque to the sub-projectile and hence making sure it spins up to the same rate as the sabot.

So it might be that this a later mark of 20-pr DS-Prac, it's certainly not earlier (see images), a Canadian variant of the 20-pr DS-Prac Mk. 3, a later Canadian variant of the 20-pr DS-Prac, or some other DS-Prac sub-projectile.
