Oh dear, I feel responsible for letting everyone know about this offer. My apologies, but as Jim said it was a risk, and this one unfortunately may not have worked out. Fingers crossed, though.
Thanks for the updates and early warning Dan. An email has been sent, mine have not been shipped yet so hopefully caught it in time. My Grandad's Trangia 25 from the 70's still has plenty of life left in it yet so I won't be needing 3 more burners! I thought I had my stove issues solved when I saw this offer, I will be needing to have a rethink me-thinks.
