30-pin to lightning adapter

I have acquired an old Bose hifi, which has an old 30-pin male socket designed to take an iPod or old iPhone. I’d like to connect my iPhone 8. Rather to my surprise, I can’t find a suitable adapter at Amazon.co.uk. Do they exist?

Apple used to offer them, but apparently no longer.

I found a couple of third-party adapters in the USA version of the Amazon app.

They seem to be plentiful on US eBay.
