Lawn Aerator (Stoke Heath CV2)

Hi. Does anyone have an old Lawn Aerator that works that they no longer need please? I have included a picture of what I'm refering to.
Looking to try and get my lawn looking a bit better and one of these would help loads.
Doesn't matter how old and rusty, as long as it does the job!
A big 'Thanks' for any replies! 😁👍 Roger
