Very Colorful Piggy Bank - Hull?

My husband bought me this piggy bank for Christmas a year or two ago. He won it from Ebay and the seller claims it is a Hull. My husband was skeptical but bid on it anyway. He liked the colors and thought it was cool looking. He also knew it was one I didn't already have. It is very colorful. The pictures do not do this pig justice. There are no markings on the bottom. Could this be a Hull? Any information would be greatly appreciated.

Thanks for looking!
