Earthshock gun measurements?

[Truro]

Hello all

Does anyone happen to have any measurements for a cyberman gun. As seen in Earthshock and the five doctors.

I'm trying to put a gun together for my cyberman costume and i can't find any measurements anywhere. Trying to find a gun has also proved impossible although i have managed to track down some of the parts i will need to make it.

Thanks in advance

I take it you've got the pictures from here, and if you have say the ventaire nozzle or in fact any major part of this you should be able to get very accurate measurements from these pictures.
