locomotives I've always chosen to ignore the lamp irons as being too fiddly to bother with and likely to be damaged by handling. In gauge 1 I don't get this option as even I would miss them.
Happily those in the kit were easy to fold up and solder. You need to ignore the convention that half etch lines are always on the inside of the fold but this doesn't seem to be a problem. Running some solder around the edge makes everything solid and ready for the loco.
To attach them to the bufferbeam I used a resistance soldering unit - a tool I very rarely break out. This time it was just the job, working far better than a conventional iron for this task.
