No4Mk1 T Can of worms

[Amatikulu]

The butt stock has clearly been over stamped. It was my understanding that when a replacement scope was fitted, the old number was either "barred" out or sanded out and the new number was applied above or below the old one. I have never seen an over stamped scope number on a butt stock. However, this is a question for P.L. or other service armorers with experience to confirm if this was a common practice.
