Vax Rapide Deluxe Carpet Cleaner (Ashby de la Zouch LE65)

I know this is a long shot but I was wondering if anyone had a Vax Rapide Deluxe Carpet Cleaner hose adaptor that isn’t being used. I have attached photos of the part I am looking for. On the last photo it’s item number 24. I have searched high and low and haven’t been able to find this hose adaptor anywhere. Thank you for taking the time to read my post.
