Ammunition chutes
These chutes are 30mm ammunition feed chutes from the Hunter they were fitted between the ammunition feed from the tank and the individual feed mouth on the 30mm ADEN cannon.
Hawker were responsible for the manufacture of the gun pack and accessories and most ADEN gun parts were 7R/ items.
Don’t listen to the riggers, they know nothing of the plumbers art of armouring!! The gun pack was a removeable item and could be changed in less than 5 minutes by a good crew. The barrels were kept with the guns as they had to have their rounds fired recorded with the gun. They were slid forward to allow the gun pack to be dropped then they were removed and replaced with the new gun pack.
To answer your original question; no these are absolutely no good for a Hurricane.
