The form is more-or-less correct for a charcoal lighter. However, even a
single use would burn off the paint and galvanizing, and produce toxic
fumes as well.
The cast parts are probably spelter, a zinc alloy. Most lamps of this
type are. A little scratch (on the back) will be yellow inside if brass,
and silver if spelter. The tubular parts are probably brass 'washed'
steel.
