I'm pretty sure this is a Taget Practice Tracer (TPT) projectile for the Modern 20x102 NATO round of US design. The "LOS" indicates manufactured for the German military in Germany ofr possibly elsewhere. It would have been fitted with an inert solid aluminium nose plug. Someone else can probably give you more information on the markings.

If HarryG is correct then:

Developed by Hispano-Suiza in the late 1940s as a more powerful replacement for the wartime 20 110 mm round. The new weapon which accompanied it, the HS820 gun, became one of the most successful 20 mm designs ever made and was widely purchased throughout the world as an aircraft and ground weapon. As a result of this wide distribution the cartridge was adopted by other designers who developed suitable guns, notably the German Rheinmetall Rh202, the French M693 and the US M139.

Hi Andy
I have a spare case or a couple of rounds
spare, no fuse or plug unfortunately

 

[Andysarmoury]

Hi Harry how much for the case and the complete round Andy

 

[Falcon]

Sorry about the incorrect ID, never take anything I try to ID as guaranteed correct.

 

[Andysarmoury]

Thats Ok Falcon there is so much to know i have been collecting for 40 years and i am still learning :laugh: Andy

 

[TonyE]

Yes, agree with Harry. It is most likely from the 20 x 139 though rather than the Hispano.
