A small item but important to the overall project is the more traditional style syringe used on the "data transmitter". Im assuming its a hypodermic needle and have found what looks like a standard size chart, will get some down time at work to do a little looking around. Of course the end result would see the cap epoxy glued to the end.

Im warming to the possibility of just putting a static replica together of the main unit, no paddles, wires or electronics,
just a highly detailed one piece unit, would make things considerably cheaper and easier. Ive got a really nice, small black slimline Haliburton that was for another project but this kit would look very cool with custom cut foam inserts in that case.
So much Bond, so little time.
