There was only 16 squadrons of RAF fighters that used 100 octane during the BoB.
The Fw190A could not fly with the outer cannon removed.
There was no Fw190A-8s flying with the JGs in 1945.

Still is. The method of generating steam has changed tho.

Heat source for steam has come a long way. Even micro nuke stations.

Thanks for the video. I've had this suggested and keep meaning to watch.

I do get to see this stuff when I'm diving. Once a wreck falls apart the good stuff is exposed for inspection and you can workout what's what after a while.

Thanks for that, very interesting and not a subject that I had really looked at.

V81 German WW1 destroyer/torpedo boat, very shallow water at around 6 to 8 meters and about 20m from the shore at the base of the cliff at Buchollie Castle

Thanks for those Alicatt. Divers with hammers! There's nothing shiny left where we dive although a friend picked up a 20mm AA roundl from the James Eagan Layne last January, the winter storms having moved the wreck a bit. He left it soaking in fresh water in his bathroom which was fine until the water pressure caused the bullet to leave the casing at high enough velocity to make a hole in his ceiling. We laughed, anyway.

It's usually triple expansion steam engines we get to see. That turbine looked interesting.

Know where you are coming from, I first dived that wreck in the late 80s but already it had been stripped of a lot of brass and phosphor bronze parts by Navy divers, part of a gearbox from her used to lie on the harbour wall at Keiss. I do have an artefact from the wreck it is a threaded brass cap from a pipe, it has sat by me on the fireplace in every home I have had since I found it.

The turbines on the ship were huge as you can see in the videos, in one of them I can stand up inside the low pressure end which is about 2m in diameter, there are hundreds of phosphor bronze turbine blades scattered al over the bottom, they range in size from about 0.5m long to about 2 cm.
I did do quite a bit of research on the wreck as it was unlisted but known by local fishermen, the Admiralty Charts had listed the wreck quite a few miles south in the middle of Sinclair Bay but there is no wreck at that position. I was in contact with HM Receiver of Wrecks about the discrepancy and subsequently they updated the charts based on the information I gave them. The Admiralty had named the wreck U-81, a German Submarine that was actually sunk off the coast of Croatia during WW2. The Receiver of Wrecks knows that I have the deck cap from the V81, I did declare it to them as part of updating the records.

The V81 was built by A.G. Vulcan in Hamburg in 1916 and she achieved a speed of 37.8knots in her trials, not too bad for a destroyer from WW1.

I was out on a night dive in Wick bay along the North Head when I came across a large object in the dark, it was a 16" shell and laying there all innocent like smile They were part of the cargo of the ammunition boat RFA Isleford that had sunk in Wick bay in bad weather in 1942, The local diving club had considered lifting the shell as it was a solid armour piercing shot, there was a considerable amount of ammunition on the seafloor and in consultation with the harbour master the Navy was called to clear it away boy did it make a big bang when they blew up the ammunition there was a water spout about 200-300ft high of muddy brown looking water with a white fringe on the leading edges of splash https://canmore.org.uk/site/321478/rfa-isleford

Armor piercing rounds contain a bursting charge as well, depending on the "mark" of shell anywhere from 50-150 pounds worth of high explosive.

The Navy divers said it was a solid shot with no explosive in it, and they left it where it lay, it was not part of the large detonation and you can still see the 16" rounds (there are 3 in total) there in about 16m of water. They are listed on the ships manifest as 16" solid shot, they were being taken from Scapa Flow to Invergordon for one of the battleships moored there.

I did find a mine there, half rotted away and a lobster creel sitting just a meter or two from it, that was the first time I called the bomb disposal, it was in 1974 and on my very first dive, that was more scary than the 16" shells! also found casings from depth charges and lots of ammo laying on the bottom. Now the area has a restriction on it and NO Diving allowed.

Ah, probably some sort of practice round then.
