Estate car dog guard? (Horspath OX33)

As part of a house clearance (and garden shed) I have a dog guard screen thing, as per the photo, that stops pets jumping from boot into main car. I’ve no idea what car it’s for, it rolls up for storage. If you are interested I can try and get more photos of the attachments and measurements. Collection only from Horspath OX33, weekday mornings only by appointment. Other items available too.
