20mm Cannon In Hawker Aircraft.

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.

HA HA

Hi Pete
Just to confirm that HA was indeed the Hawker inspection stamp,almost certainly used at langley but definitely used at Kingston/Dunsfold,dunno about stuff that goes bnag… we left that to the bombheads !!!!

In response to part of your question “My info says the hunter had 30mm?” – yes the Hunter was equiped with 4 x 30mm Aden Cannon with the ammuntion feeds built into a removable gunpack (the cannon barrels remaining fixed into the airframe)

Part numbers

The latter two would be much prefered, Jets look cool and can do some pretty awesome stuff in the air but its pistons and props all the way for me.The chutes have some other numbers which might relate to the type of cannon or possibly aircraft. If each instalation is unique they ought to have some clue in the part number. Do you know what type of cannon ie MK each aircraft used? Did hawker use a part number system like supermarine. ie 300=aircraft type next XX= system and third XX=individual part number ?
Part numbers should be an easy key to unlock part identities but the British Wartime system varies hugely. German numbers as i understand it have the aircraft type on every piece and they have a national numbering system. (not individual manufacturer) Herbert P could probably correct me on that.:confused:
I have quite a few bits which are very obviously wartime with clearly marked part numbers but i cant get near to finding who made them. Possibly the inspectors ID stamps are a better clue? I know after digging a few bits from a dump Bristol aircraft have FB preceding their part numbers.
The chutes probably carry some hispano numbers as i bet they were made by the Cannon manufacturer. They were probably inspected prior to fitting and stamped by a Hawker engineer to say they were OK.

Well, they will have been made by the Hawker factory at Langley. The original stamps were being used until the demise of the plants, so anything made at Hatfield used DH inspectors stamps up until the end of 146 production there. That said, they are probably from a Hawker product; Sea Hawk would be an intelligent guess, as would Sea Fury or Tempest.

cannon

Thanks Bruce, am i write in assuming they are hawker having HA within the quality stamp? any ideas what they are from?

All the 20mm set ups are different.

The postwar 20mm cannon is a completely different beast from the wartime one, and they are not directly interchangeable.

Tried to put one in a Spitfire once; it wouldnt go near it!
