Experimental 105 Tk cartridge case

[Tsarbombaad]

Hello, I have this 105mm cartridge case that has purple markings on it, which I think may mean it was experimental. The top section of the case has been cut off (with the projectile I assume), which may mean this has not been fired. Anyone has any idea what it could be referring to?

It should read -
REQN MVEE 80566
ITEM 3
C.W. 5LBS NQ/M 032.

REQN - I've always understood this to be "Requisition"
MVEE - Military Vehicles and Engineering Establishment Chertsey (This came as a great surprise, as I grew up knowing it as Chobham and visited "Chobham" in the early 70s)
80566 - The order number

ITEM 3 - Presumably a specific item identifier

CW - Charge weight
5LBS - self explanatory
NQ - Cordite NQ - Cordite with a high percentage of Picrite (picrite is easier to spell than nitroguanidine)
M - denotes the cordite is in multi-tubular form
032 - the mean difference of the thickness between webs (in thousandths of an inch)

Normally the markings would be made with silver nitrate resulting in black characters. Using paint is problematic as it can cause all manner of problems in the chamber.
