https://www.ebay.co.uk/itm/261067328695A few came up when I searched, this one was close to the top, but they had what I wanted, the price was OK and the seller's feedback was good, so I didn't bother looking any further.
What were you doing posting at 05:51 - couldn't sleep, or just come home?
Edited to add, as an aside, that I highly recommend the 5 litre water carrier on the Speedster website. I've had one for a few years, ideal for wild camping, no plastic taste, weighs 67g and folds flat, taking no space in your pack.
