Cowcatcher steam harpoon

Decided the cowcatcher on the main ship looked too plain.  Had wanted to mount a harpoon somewhere that could be used to snag an enemy you were chasing.  When it is mounted on the ship, there will be a cable that will be attached to the harpoon with a reel mechanism.  The rangefinder lense is from an 8 mm camera and is still operational, diaphragm will open and close.  Steam tubes to fire it will be added when it is mounted on the ship.

Added a control mechanism on the right.  Part from an 8 mm camera.   Built a canister in the rear as a steam pressure chamber.  Turning the cogged wheel on the right turns the wheel which allows more pressure to the cannon.  The gauge is set according to the distance found by the rangefinder which allocates the correct amount of steam to not overfire or underfire the cannon.  Pressing a button on the back of the mechanism sets it back to S or 0, it is fully functional
