Here is a picture of the handguards
Attachment 71807
About the pattern of the rifle and according to my knowledge, I am asking myself:
looking the butt socket (see the markings picture) I can see the star lined out after the III.
Looking the rifle I see the correct fore-end, the cutoff device, the rear sight with windage, just the plate of the volley sight, no unit disc but not sure if taken away in arsenal (found vinilic glue around the wood disc)......is it a MkIII without some parts or a MkIII* somehow aborted??
