Alpino S rear grab handle

Hi all
Im nearly finnished a complete restoration of an Alpino S 500 but am having lots of trouble finding (if you can at all) the rear L/H side grab handle that helps you put it on the centre stand.
So wondering if anyone out there might have one they are willing to sell. Happy to pay the price.
Thank you all for reading.
