New one one me Brit amphib tank

That looks a lot like an LVT hull with a cruiser turret.

 

That's about the only way one can have an amphibious tank. The Marine Corps Equipment Board ruled against them in 1934, because they could not be expected to survive the open sea 3-6 miles offshore. The evolution of the amtrac altered that but only slightly. Once out of the water, they are vulnerable targets for direct fire.

Did they use DD Shermans in the Pacific?

Is this an amazing survival or a replica someone made?

That's neat, I did not know rake plows like that had been around that long. I assumed they were a relatively recent thing.

Too late for anywhere but Okinawa.
 
The T6 flotation device, much better seaworthiness than the DD tanks using curtains. However the flotation pontoons could be caught by reefs at low tide, etc., leaving the tank stranded.
 
 
...The T-6 consists essentially of six steel pontoons;one pontoon on each side of the tank, one on the bow, one on the rear, with bow extension and rear extension pontoons which hinge upward for more compact stowage prior to launching. The six pontoons are compartmented by sheet steel partitions into many sub-compartments; Sub-compartments are filled with plastic foam-to further ensure buoyancy should the pontoons 'become punctured.T-6 floated tanks are seaworthy, having been success-fully tested in twelve foot waves. The floated tank is forty three feet long and therefore provides a fairly stable gun platform, enabling a tank gunner employing the gyrostabilizer to deliver accurate fire during the beachapproach. Compared with LVT(A)ts (amphibious tanks), the floated tank constitutes a more stable gun platform; the higher velocity and greater accuracy of the stabilized tank gun in comparison with the LVT(A) howitzer and the tank's heavier armor, are important advantages. Pontoonsare jettisonable form inside the tank on reaching the beach. Pontoons are remountable and can be reused.T-6 devices, as used on Okinawa, generally provided adequate flotation but needed further development to improve steering, to increase speed above the 4.2 knots obtained by the tank tracks revolving in the water, and to provide a reverse...
 
 
The USMC tanks landed at Okinawa from LCM and LSMs, except for one company each in the 1st and 6th Tank Battalions which used the novel T6 pontoon device to swim  tanks into the beach, using their tracks as propulsion.  Sometimes, they struggled to get over the reefs, but they did in fact function as designed, and the tank crews detonated explosive charges to shed the pontoons and went into action, albeit a bit low on fuel.  
 
 
 
One T6-equipped tank apparently brushed with a destroyer, causing wags to claim the only instance of such a collision at sea;

It does, but the tracks show that it was not a direct rip off.  Form follows function though.

Good catch.  My eye wanted to make the photo distorted, appearing 'squeezed' from the sides (or ends).

They seem to be demoing the vehicle to Spanish time travellers from the 17th century.

ATI* at Barry Island, based on the Covenanter and using its turret. It was the first of three versions (the others being ATI** and ATI***, of course), and this one was unsprung. The flanges on the track shoes were used as paddles, according to Fletcher, and this machine was eventually scrapped by Curran Bros. of Cardiff.

Tiny bit of trivia I just discovered. Curran Bros built (presumably converted) 60 Matilda Baron Mk IIIA mine clearing tanks.

Whenever I see the dumping of AFVs into the sea as artificial reefs or divers' trinkets, I think of the tens of thousands of soldiers of all descriptions who sweated and bled for decades to keep them in code A condition, including this M48A5.

I can't find the clip at the moment, but in the "reality show" Axe Men on The "History" Channel, one of the lumberjack teams had a crane whose chassis and drivetrain were that of an M4 Sherman (one of the lumberjacks commented "That's the tank that won us the war!")
 
Anyone remember it?

Yep. They're out there. A company in Augusta, Ga (SECO) built some of this sort of stuff for logging (Drag lines), mining and such. I think they usually used M3 chassis instead of M4s as there was less to remove above the hull. But you can also find bits and bobs based off of the various High Speed Tractors and M5 Stuart hulls too. OH Sexton Hulls as well. SECO had a final batch of 6 Sexton Hulls that I lent some Brits tools for the recovery of.

Five years ago I saw a drill rig in Nevada over what seemed like a HVSS M4 chassis. The volutes in the suspension had been replaced with coil springs - I'm assuming because of the loss of most of the armor.
