Years ago I had 2 of the original trangias, god knows what ever happend to them, my guess is leant em to a mate who decided to keep em.
Anyhow, I have the swedish militry version, thats damn good, I made quite a few of the ol coke can burners they work a treat, I just seem to like this style of cooker.
btw I believe the kettles are sold seperate for trangia, (daughters college had a talk for the D of E kit few weeks back, kettle was included, when the shop givin the talk showed it all off, college purchased a load then discovered kettles were extra hahaha) if your after a kettle that fits, the tracker or chub fishing kettles should do the trick, my daughter borrowed mine and it fitted quite well and packed away inside the trangia.
