New/Old lighter

I found this Dunhill service lighter at a neighborhood antique store...

Aside from the paint coming off the outside it is practically new


I popped a flint in, filled it with fluid, and it lit on the first strike. Pretty cool; but not too handy to light a pipe.

Does anyone know what metals were used for these? It is kinda blue like stainless; but that metal seems wrong for that timeframe?
How did that trench lighter work for ya?
