To compliment my Trangia 27 I was after a 2.5 ltr billy. I looked on line and stumbled across a Trangia 24 cookset.... never knew they ever existed until now.. I looked on Youtube to find a guy demonstrating the Trangia 24 and all it has in the kit. I was willing to just buy the 2,5 billy can, but for a few pounds more you get quite a few extras .... So, along with the 2.5 litre billy you can the 25 size kettle, the larger 25 size pot, pot grabber, strap and frying pan of which the billy lid fit very nicely to.
