No. it is not a Cornwell cart.

Cornwall doesn't make carts. With the exception of their newer top of the line carts which I think are made only for them, any other Cornwall cart can be bought under 20 other names.
Waiting for the poster to ask why you didn't buy the $99 cart at HF!![]()
So it's possible this cart may have been sold as a Cornwell but manufactured by someone else?
100 isn't bad for the cart in any case, so I wouldn't fret.
