Well I've had chance to strip the scope down and to my untrained eye the internals appear to be the same as those in any other MkIII scope.

I've also removed the soldered half rings from the Ocular end. They are made from Brass and have been perfectly shaped to fit around the Ocular bell, definitely not a home gunsmiths work so I'm wondering if it was for a Military purpose of some kind?

Cheers,

Simon.
