Undo the top nut and remove the strut to reveal all....
Bear in mind if you do this and it doesnt already have an insert in it ie its the original shock it will be ruined and need replacing as you will have broke the seal. The original isnt a seperate self sealed unit link the new inserts.
From the pic you just posted it looks like the pre 85 Boge with the aluminium lock, the later ones have a steel lock that screws onto the outside of the strut not the inside. Its a shame as I chucked out a set of these a few weeks back otherwise I could have taken some pics for you to compare to.
