Picked this up today at Waterloo market
20mm Hispano case with unfired TPT projectile.
Case is stencilled
`20MMTP T M71A
LOT 1 ASM 80 `

No problems there & I take the 80 to be the year - BUT - headstamp is:
`DAC 44 20mm` So 20mm 1944 by Dominion Canada.
Is this a 1944 case used as/for TPT in 1980?

Hicky,

I also got one of these DAC cases, but mine is from 45 and the projectile is marked 1976.

The M71 HIS SUB round was a TP-T round used as subcaliber for the Belgian Leopard tanks.
It was fired from a bolt-action barrel, mounted on top of the barrel (and there was a second, later model that fitted inside the barel)

My guess is that ASM (which was a Belgian munition maintenance depot) did use 'old' casings to make these training rounds.

That all makes sense as i m in Belgium.
Makes another `tale to tell` addition to my collection.
Were these post war surplus cases then? Or reloads?

Hi Hicky,
I have one of these with the same type of TP-T projectile as yours,also in a DAC 44 case,but the stencil on the case identifies it as a M80.....'20MM TP-T M80BG LOT 01 ASM 89'.
The M71 projectile in Orpheus photo looks a whole lot different to the ones we have.....could you have a M80 projectile in a M71 case?

I did wonder about that Tony - couldwell be the case!!!:tinysmile_hmm_t:
Might have a look and see if I have an M71 proj

 

[orpheus72]

There were (as far as i know) 3 types of these HIS SUB rounds: the M68, the M71 and the M80.
All have a diffrent type of projectile, but all are TP-T and used for the same purpose.

I've added pictures of my M68 and the M80 (the M80 picture comes from BOCN-member hasag's collection)

Thanks orpheus,
do you know what the 'BG' refers to on the case stenciling ?

Tony,

The BG suffix stands for "Belgian" (readable in all three national languages Duch, German and French)
It can be found on most ordnance related items produced by Belgian manufacturers for 'domestic usage' (see pics)
