Unidentified 155MM projectile


Good evening everyone, i’ve got a pretty quick question for the bigger caliber ammunition collectors.
Recently i acquired a 155MM projectile, i cant seem to find out what type of projectile this is.
The only marking i can really read properly is D563.

Any help is highly appreciated.


The 155mm D563 is an ICM M483A1.


Here a diagram:
