The scope is very interesting...
It's a 1943-dated M38, which would have originally been fitted to a Sherman tank. Nothing unusual there, but this type of scope was chosen for the E-11 Blasters used by Empire Stormtroopers in Star Wars. The E-11s were actually British Sterling SMGs dressed up to look futuristic. As you know there's a massive Star Wars industry and today you can buy replica M38 scopes in resin, or even metal, for your very own E-11.
So, has anyone got a Sterling SMG we can butcher?
