Checked the nearest Homebrew shop to see if I can get some tomorrow... he only has 29mm Belgian caps in stock!
Checked Amazon, soonest delivery is middle of the week (ordered them anyway!)
Ended up doing this:
That's a 5L stainless steel growler/keg. I primed it to naturally carb, and I have a picnic tap and a little CO2 cartridge setup to push it out.
