Cast iron/metal parasol base (Anstey LE7)

Hi, does anyone have an old heavy duty cast iron or metal parasol base they no longer want or need?
I dont like to buy brand new if I can recycle and upcycle. I dont mind if it has a bit of rust or needs painting. I actually want to use it for my rotary washing line as I have a stabbed yard and like to move it around x

Thank you so much in advance ☺️
