The Archaeology Thread

How about some WW2 experimental aviation stuff?


An experimental catapult designed to launch World War Two bomber planes into the sky has been excavated.
The prototype Royal Aircraft Establishment Mark III Catapult was unearthed at the site of a development at the Harwell Science and Innovation Campus in Oxfordshire.
It was made to enable take-offs using shorter runways and so the planes could be loaded with more fuel.
The contraption was built between 1938 and 1940 when the site was RAF Harwell.


However, the project was abandoned without ever launching an aircraft, because the engines would wear out and the design did not properly fit the bomber planes.

The technology was a precursor to Catapult Armed Merchant (CAM) ships, which launched Hawker Hurricanes at sea via rocket-propelled catapults.

Beat me to it!

It's not summat I've heard about though, RATO yes but not catapults though it does make sense.
Ah well, there’s no shame in being third. :D
Can definitely see the logic in the development of the idea, but can also see why it was abandoned.
At least with all that concrete there’s no problem keeping the section straight, but imagine shovelling/barrowing out the circular bit?

Kinell, how many times have you been told to keep the section straight & not to chase features! :D
 
Spigot mortar for defence?
@Listy , please expand on this!

Likely a normal holdfast.

Just google 'Spigot mortar Emplacement' and there'll be hundreds of pictures and links. I'm not being snarky here, its just there's so many pictures of the millions of different designs I could be posting links for the next six hours and not get anywhere. The above link was one I randomly grabbed from the front page of google. Lots of local history associations have looked at their and put it on the web.

It's a concrete pedestal, which a Blacker bombard could be plonked onto to provide a firing position. Usually sited in triples, so if the gun was detected it could be lifted up and moved to an alternative firing position. And usually within 500 yards of an choke point. I've seen several posted and in most cases when asking the photographer about the local area there'll be a bridge, dip in the road or tight corner somewhere nearby which the position overlooks.
Over 18,000 were constructed during the war.

You may be wondering why there's be a predominately HG weapon on an airfield, that was likely down to how Airfield defence was organised during the war. Each airfield had a Station Defence Officer. his Job was to oversee the local area defence (including close in AA) with Airmen taken from the airbase. He also liaised with other local forces. It's quiet possible that as it was a high value research site the Station Defence forces had extra firepower, or maybe they got the local HG to deploy one of their mortars there.

Of course all that assumes that the identification of the Spigot mortar site is accurate. It could be some lasses washing line fastening point miss-identified by a journo who needs to be told who won the Second World War for all I know without pictures.

Yeah that's a spigot site. Almost textbook. The recesses in the walls were ammo bays. Enemy expected from the direction of the top right corner. Obviously going to be held by the green fencing :safe:

Interesting the Holdfast is missing.

As an addon, I just stumbled across this:


Clicking on the MOLA link got me to their archive of 3D models. I may spend some time here later...

 
It was found within 50m (164ft) of a Tudor silver gilt hooked tag by the same detectorist near Frinton, Essex. Miss Rogerson, the county's finds liaison officer, believes the items were probably lost at the same time

Why? And this gets me. They have been in a farmers field for 100s years.


As the ring is battered and cracked and the hooked tag damaged, Miss Rogerson believes they may have belonged to the same person who was taking them to be recycled at the time they were lost.

As someone ho's dug up more than their fair share of battered and cracked artefacts (but no gold!), I wonder why the FLO thinks that they were being taken to be weighed in? I would have assumed that apart from the expected wear an tear from daily use, some of the damage would be the result of being buried in the ground and occasionally given a good churn by a plough or rabbits.
