Markings on 20-pr APCBC Shot

[Depotman]

I have an unfired 20-pr APCBC shot with very few markings. I wonder what they signify and if it's a trials or pre-production version. I haven't found any detailed drawings of the shot and I question whether the rifling is 'Probert' and if the rubber 'cup' at the base of the unit is standard.
The stampings are:-

MA O 68 37 and a small '2' just above the driving-band.

The stencils are :-

AP/CBC 20Pr MK1/2 repeated on two sides of the shot body

LOT 2 MA 95837 AB repeated on two sides of the shot body

There are also some red stencils unfortunately illegible.

Photos follow and I would welcome answers and/or comments!

Thank-you very much for the drawings -they confirm that my shot is a standard build, apart from the stampings, which don't seem to conform to the stampings on your drawings, or to 'standard stampings seen on other 'heads' of a similar age. Nearly cracked the problem!

Trevor,
Yours is an Australian one. Several of these are known in collections, and as far as I know came from the Proof & Experimental range at Eskmeals.

Regards,
Roger.

MA is the code for Lithgow, NSW but I did not think they made large projectiles .

Thanks Ron, another one of these items where the full identification is like a jigsaw puzzle!

Thanks for the photos. I think many items are just museum displays and not made at Lithgow?
I know they made bombs and mortars but I need convincing about large projectiles. I need confirmation on many items.
