My first attempt for making a life size replica of the Hypo used by McCoy in the original Star Trek series. This piece is solid aluminum. The bottle unscrews from the back and is replacable. The Hypo even hisses as you push it closed.
I studied these hypos extensively for an SDStudios replica some years ago. I actually identified three variations: from top, season 1, season 2, and a hybrid version that appears in a few episodes (Patterns of Force being one, if I recall)
Note that the season 1 injector tip is designed differently, with a split "tongue." Also the finger guard is cosdiderably shorter. The medicine vial fits down father into the tube on the later season version.
Yes... I realized how bad my first attempt was. I teamed up with a 3d artist and found a CNC shop to help with the project.. here is the new 100% screen accurate season 2 we have come up with.. completely field strip-able made from measurements of the actual screen used prop
Still needs to be finished and polished... now working on a perfect season 1
