Another long term mystery pot help with Identification needed

Whilst i'm on a roll here is another pot that remains unidentified. If anyone can help that would be great. Measures 12 inches high and weighs a ton 2-3kgs may be more but too big for kitchen scales. Even if you can point me in the direction of similar that would be great. I also have a slab vase that I will also post fingers crossed i can solve the mystery of one!! thank you

My first thought is Alan Wallwork
My second thought is scrape the bottom and see if there's a mark.

Third thought is Terry Davies
Fourth is Barbara Cass

Thank you NaomiM Great minds! as i was photoing it I thought the same shall i scrape the bottom! As it has been warm it is a little bit soft so could be a good time!! I will look at the other potters. Just uploading the slab vase as well, let me know what you think. Sam

I personally think both this one and the slab vase are student pieces   

Hi big ed, may be, it would solve the mystery! what makes you think that ?

I don't mean to be derogatory Sam, but they look quite crudely made in an amateurish way , certainly nothing remotely like Cass work in any way at all , but only imo , Ed

Not a problem big ed was just the type of info i'm after as I don't have a clue    All opinions welcome so I can stop wondering every now and then where they came from. They have been driving me pots every now and then spending hours researching!! your imo much appreciated Sam

I think it's a great piece. Have you scraped it's little bottom?
