A Mark V in Luhansk, Ukraine seems to be the only other British tank serving as a memorial, rather than a museum exhibit. There are quite a few FT17 scattered about. See here: Lists of Surviving WW1 Tanks
He's also got lists of WW2 armour.
I have a photo in a book from my local town, (Denny in Stirlingshire). It is the tank Juilian, on 15th October 1918 and was there as part of the East Stirlingshire Tank Week to raise money for war bonds. The tank was commanded by a Captain McIntosh.
Funny thing, "the first ever tank was designed and developed, in, Lincoln" in 1916. There's hardly any testament to that fact, apart from an obscure plaque somewhere on Lincoln's Tritton road, if that hasn't been nicked and sold off by developers, or "incomers".
There is a bit more in Lincoln than that, at the top of the hill on Burton Road is the Museum of Lincolnshire Life they have "Flirt" tucked away inside amongst all the agricultural equipment, from memory (going back at least 10 years since I visited) it gives quite a lot of detail as to how Tanks were developed in the town from farm tractors etc.
If you look carefully at the 'skeleton' tank, you'll see that it bears only a fleeting resemblance to the real 'war babies' of WW1............the tracks are neither the correct width or configuration so I would suggest this was some sort of concept tank that the Americans came up with? Could be wrong but, I think not??
