Hi Grumpy2,
Thanks for the reply. I've actually posted a reply to my own OP with the pictures in (checked this time), but the post hasn't shown up yet as I think it has to pass moderation. Hopefully it will give an insight into what I have.
I'm returned a favour to my friend by trying to find a home for it but having seen another post I'm not sure it's worth too much money. There's zero corrosion on it, just witness marks from the stainless feet.
