The Isis Adventure

Hello,

Ive finally found my isis again so thought i would have a play.

i managed to get the two halfs to start unscrewing but it got stuck at about half way, i did it back up but now the two placates wont line back up, but the plunger goes all the way down and i cant hear any of the ball bearings inside.

Any help or suggestions would be a great help.

Thank you

Hold the Plunger down and turn the two halves until the placentas line up
