went on a little digging exploration for this one. Good luck mates!
A tricky one. Amphibious, clearly. Although there are some features that look anomalous to me, I would suggest that this is a Vickers Armstrong Amphibious Light Tank. Vickers produced two prototypes of this vehicle; this looks like the A4E12 (LIE2) version. This was a “commercial tank” project. It was offered to the British Army, but they were unimpressed with various aspects, including ease of control, light armour, light armament … They may not have been too impressed by its amphibious abilities, either - I have seen a few photos of amphibious trials of this vehicle, and they would not inspire confidence. I would infinitely have preferred to drive under a swamp in a T-34. I believe that Vickers - after all, a commercial tank manufacturer - sold a small number of production versions to Nationalist China. No idea how they fared there - perhaps it is as well that the traditional way to get across the Yellow River was swimming … Best regards, JR.
Quite nimble really - a little bit rear heavy when it swims

What a cool little Tankette. Agree about the balance issue, one good tip, and that might be it. Would be good for some fishing though. 
Pretty sure that’s what it is.
Would be good if ,
Sorry mates that it took so long. I’m only on in the mornings unfortunately but yes JR is correct! Nice job JR and now it’s your turn.
Thanks, Kilroy. I’ll try another oddity. What might this be ? Best regards, JR.
The answer is written on the side
TRACKLAYER C.L.B. 75
Made by CL Best in 1916 or 1917 (some debate over the years about it being a Holt 75).
Yes, leccy my friend, that is what it is. This is in fact a mockup, and an example of one of the tank’s origins in early US agricultural tractors. The attached image shows how it was supposed to work. The only photos I know of that exist are supposed to relate to manoeuvers by the California National Guard in 1917. In any event, the US Army does not seem to have been impressed, and the project was not taken up. No production versions were outcoming. Best regards and over to you, JR.
Just to see if anyone knows or can drag out information about this beast and what particular use it was intended.
Driveline, and suspension components of the M-4 series vehicles were commonly available for civilian use. The machine shown in the image is not a Sherman, and probably not Military,but commercial. Just a fair number of components (early ones) used to produce a commercial construction machine, not easy to be sure, but this looks like a Bulldozer minus the Blade, and side arm bits. Also, it has only two suspension stations per side, and one of them is reversed. All M-3, and M-4 Hulls had three stations per side. The square mount shown in the image could be the mounting point for the Blade, and it’s arms. As to what it was called, so far, no idea. Many Sherman parts were used to make Logging, and other construction machinery, due to their versatility, and low prices as surplus after the war.
I want the bottom left one. I’ll trade you my Subaru for it.
If it’s a Subaru 360 you might have a deal… 
Oh it is a Sherman - heavily re-worked and produced for a specific purpose post war, I will give a clue in that it was produced by Vickers using Sherman III hulls and parts.
Can’t wait to hear the story behind this one, ( I bet it’s the SP-III Tactical Haggis cooker) 
Maybe it is a little obscure, produced by Vickers for the British ill fated ‘Groundnut Scheme’ in Africa
It was called the Shervick, at the time no commercial bulldozer could cope with the particular type of scrubland in the area so Vickers were asked to produce one - the Shervick (for which an order for 500 was initially placed later increased to 1000 but it is not known how many were actually made). It was an interim design while Vickers developed their own from scratch (Vickers Vigour) which saw limited use as it was powerful but complicated and expensive.

Good stuff.
Uh… I think its Leccy’s turn. Have at it mate.
Since Leccy has not posted, allow me to keep the ball rolling with this entry. Now, this may, or may not be very easy, but in any event there is a premium offered to the successful answer.
I have a copy of the book American Sniper written by Navy Seal Chris Kyle, and it goes to the first correct answer posted. Sent to the winner at no cost to them. (just need an address to send it to) The book is in English, so if you win it, I hope you can read it…
