Pulley clothes airer (Micklefield HP13)

Hi, My grandsons pre school are looking for a clothes airer to hang the tarpaulins and wet gear from forest school on, instead of putting them in the shed damp. Does anyone have one of these they no longer use ( or a broken one we can fix) to make the shed less mouldy and the equipment last longer. I can collect to suit you. Many thanks. Regards, Sue
