For starters...

It should have a Mk1 sight modified to T spec, not a MkIII. The scope is m/m. The seller claims birch, looks like maple of beech to me, either way - it should be walnut.

The mount is either missing a screw, or the screw is twisted off in the receiver (broken).

Looks like a put-together to me. Also, the most important inspection stamps are not shown in any pics.
