20 Pr Rocket head.

I have this unknown rocket head possibly for a 3" Rocket but it has odd stampings. (in 2 lines). These stamps are too light to photograph clearly.

AP CBC 20 PR MK 1/2
LOT 15 CSC 6 60 BS

This is painted on the body by some previous owner? Obviously it does not have a ballistic cap and is AP.
The base looks like a tracer but this would not work in a rocket. Maybe a 20Pr projectile was converted to a rocket head. Looks British made.

Weight is 7.06kg (15.6 lb) so not 20 lb. Who is CSC maker ?
Diameter is 83.7mm (3.3")
Head length is 185mm.
Overall is 226mm.
Threads are 67.4mm across and 12 TPI Whitworth.
Base hole is 62mm deep and almost 12mm diameter.

I am keen to find information on this item as it is not listed in my books. Only 25Pr AP rocket heads.

Hello,
Maybe you search on the wrong way.
I think it's an uncomplete artillery shot 20PR APCBC (missing : balistic cap, band and base cup)

I had not seen a cross-section as shown of the 20Pr APCBC with the threaded part at the base. You are correct so many thanks.
