BOCN Guess what it is

Is it a Cox Submarine Gun?

No but I googled the cox gun and it is very interesting. Several members guessed this device on other unknowns so I though there might be an interest. Ordnance knows and has one of the few actual collections of these.
 
Correct. It is a Cartridge Engine Starter No 10 Mk 3 Engine Run Up (ERU) for the Rolls Royce Avon engine used in the Hawker Hunter fighter and the Canberra bomber. Your turn.
 
For use in oil well drilling, I believe. I think I have some of the projectiles around here somewhere.

A Dardick Triplex Tround
 
You guys are good.
Both Snufkin and Slick are right but I have to give this one to Slick as he came up with the whole answer and said exactly what it is.
Over to you Slick.
Dave.

Feel free to post something if you have an available piece. Otherwise, it'll be late tomorrow before I can. Thanks.
