Please could someone tell me whether they are a Pit Bull? i have seen one for sale and i could do with knowing more about the breed.

no offence but why not just look in the net?u can ask people all u want but you dont know for 100% if the info is correct.
no they are not a pitbull at all.
theres 4 main strains
flynn strain,pyscho strain and stormer (sometimes mixed)and dublin red strains which are much rarer.trhe pyscho stormer are the most common.

The main problem is that they are of the pit bull type (which is illegal) and may therefore be picked up as such and as they are not a recognised breed it is difficult to prove they are not pitbulls. Think they have been developed to replace pitbulls but that is just my opinion.
