An agricultural antique in the form a single furrow plough nestling in the corner of a barn. At the time this piece of equipment was produced it was absolutely state-of-the-art, now it would be a piece of equipment for an agricultural hobbyist or an obsessed smallholder. Or a garden ornament.
This time the plough is owned by a farmer, obviously, who has retired and just can't bear the thought of parting with it because of the memories it holds for him, which seems entirely fair to us.
Times march on and now the ploughs behind the might tractors have fourteen revolving blades.
Just what you need for your allotment.
