HAL brain-key

My interpretation of the handle of the key used by astronaut Bowman to deactivate HAL in the 'Brainroom' scene of 2001 (the little key that makes the clear acrylic blocks pop up).
You have to provide your own key, I'm afraid (until I get more time on the work computer and can draw up the key shaft to suit). It's a Burg Wächter type E7/3. Check out prop-making site therpf.com for more detailed discussion:
