Help 20x102 French

Hello,

As you know the blue color is for a practice round.
It's the practice version of AP-T ("OP-T - obus perforant traceur").
I assume SPT = "simili perforant traceur" (=simulation of AP round )
I know nothing about the gun used.

Regards

Thank you MINENAZ16, but the shell is not plotter, and his letters in yellow in the 68 years the NATO France use the code?
What Makes Our letter in the yellow?
Saludos
 
Is the 102mm case the right one for this projectile, maybe-128mm or -139mm,or even 110mm?

Hello,

In the sixties, I don't know why but marking for practice ordnance were yellow (other examples in pictures).
Now markings are white.
Normally markings are the initials of the complete nomenclature.

Cheers

It looks like a french 20x102mm for a M621 gun.
In the 68 years, there was a lot of test in France with the munition for this gun.
I have not explanation about the code SPT and le yellow color.
I keep seeking !

Here are 3 cartridges of my collection:

The middle one is linked to the development of de munition for the M693 weapon
It use a 20x102 projectile mounted on a 20x139 case
The projectile is marked (yellow on blue):
20-693
LOT 23 A T E 70
I don't know more on this cartridge but the connection with the hasag's projectile is real.
I think the marking SPT does not linked with the type of projectile but with the weapon, probably exprimental, who should use it (20-693 : 20 mm for the 693 gun on my cartridge)

Very interesting Maverick1112003, merci beaucoup :)
Nice Photo
Remains whether the projectile that amount 20x102, and SPT is?
20-693 = 20x139
 
hello
i had the same cartridge with the blue projectile
it appear to be a test for high velocity with this lighter projectile
 
I recall finding TP items with Yellow stencils/markings - then changed to white.
Possibly NATO standardisation? Yellow usually being related to HE? (in general not just markings).
