This is definitely not a carronade. However, it may be that the photograph was distorted by the book-producers to fit the available space. The carriage looks rather low. Early carronades were mounted on normal trucked carriages. Also half-trucked carriages were used sometimes, I think in particular in France. But then quickly the slide carriages became common for them.

Carronades will happily throw shot beyond that which is considered useful for guns. (This requires more elevation than guns, but this also helps partially limit the problem for carronades from the dispersion increase given by firing from an unsteady platform - the roll taken as being the same, the effect on range of random fire for the gun is greater in direct proportion to the help given by flatter fire in the increase of the danger space - making the defect arguable at best... with ricochet fire the short hitting space of lower velocity guns is less important too - with shot weight giving a longer working distance in ricochet).

Penetration/shot effect at range strongly favours high calibre/weight over high velocity - with a 42pdr carronade shot penetrating 21" sides at ~ 1700yds, while a 12pdr gun shot with distant charge maybe reaching only ~ 900yds, albeit at a higher velocity and a flatter angle of fire. This also serves to make ricochet fires more attractive to extend useful range for heavy shot (despite the additional loss on each rebound).

The "problem" for carronades on the lakes was the meeting of 24pdr carronade broadsides (or hodgepodge armaments with many 6, 9 and 12pdr guns) - with 24pdr and 32pdr long guns on pivots, and 32pdr carronades, where there is no compensating benefit from shot weight, and an absolute penalty is all aspects of long range fire.
(Also oft quoted examples have the problem being well within carronade range but anchored and unable to retain springs - so taken apart from the quarter "where not a single carronade could be brought to bear" (alternative rendered as 'no carronade could reach' - both of which are also incorrect/incomplete given the actual report of damage needing repair given by the carpenter's report describing both RN vessels, and the USN prize (and the armaments of the Cherub being 32pdr and 18pdr carronades, against the 32pdr carronades of the Essex (with no indication that this was only a single ship action as Cherub could not fire)).

How does that gun class as a 32 pounder? looks like a 3pounder or less

Mostly, carronades were used as broad-side guns, whose carriage was pivoted at the front. However, the sliding carriage could also be designed with a pivot in the centre, so that it could be rotated through a full circle, when mounted on the centre-line of a ship. I gather that this what is meant.
 
However, I doubt that using a carronade is a good proposition for this. Carronades are short-range guns and as such would have a considerable muzzle blast, which could blow away bulwarks and damage the deck-planking. Normally, long guns were used in such positions.

When the author says a swivel, I think he mean a single, large, centrally-mounted pivot-carriage. Chances are too, that the unusual-weight 48-pounder is not of a true carronade pattern, but a short-barreled siege howitzer.
 
Where is that picture from? It is so misidentified! And why is such an important historical piece outside in the elements?

Note how the text also says there is a breeching loop, of which there is none..

This photo is is not of a carronade! It has been utterly misidentified. The photo is of a half-pound swivel gun on its original mount. If you tried to mount a 48 pounder carronade this way, it would blow itself off such a mounting the first time you tried to fire it! In the description, it is obvious that the powder was 'bad', or this would have undoubtedly happened to the merchant. 

Thank you all for the quick response.
You confirmed also my doubts about the 32pdr "carronade" in the photo.
The photo is from Osprey Publishing "Napoleonic naval armaments 1792-1815"

 
and there is another photo on page 7, for which I would like to read your coments...How a long barrel gun, can defined as "caronade"?

Thank you

Hello all.
I have found a text and and an image on which I would like to have your comments please.
The below text says about a 48pdr carronade on a swivel! Is that posible or it means something else?

The below photo is described as a 32pdr carronade and is shown on a swivel. How come this gun is defined as "carronade" and could be a 48pdr carronade attached on a same-similar swivel.

 
Many thanks in advance.

All the above that Phil said and just another tip that should  also be considered. The storage and the treatment of the tape, every time after the use of it. 
If you thowing it away (as I used to do), or keep the tape on the bench being hit by other stuf while you are working, the edges of it get curves.Then the dust gets in and  you might have weak glued points on the surface of the hull. 
I use an ordinary masking tape on my models, but to eliminate any misfunction or misstreaement, I create a new strip-edges  on an initial strip of  it, by using a ruller and a sharp cutter on a plate of glass.
