Rusty Old Plough??

I'm not good at keeping up with Blip themes and challenges,  but after Flower Friday I have stunned myself by  finding something derelict on a Sunday. I've walked past this tree many times but there are usually sheep sheltering beneath it. Today I realised there was an  old bit of rusty farm machinery growing into the tree!!  Do you think its an old plough? Look at the left hand side handle its right through the tree and sticking out the other side. .   How long has it been there I wonder?
And thank you Marlieske for keeping track  of us all so I know what number to tag.
