Wow! I love this picture! Where in the dickens did you find it, and where was it taken?
I think the old reliable flint and steel continued in use for a long time among the country folk of eastern and northeastern Europe. This interesting lady looks as if she might have lived in that part of the world.
She shows good form in manipulating her strike-a-light.
I think her striker may be a somewhat angular variant of the "0" shaped steels, although we can't say for sure what the part clutched in her fingers looks like. The online database for the Finnish National Museum shows a variety of European fire steels. Maybe I'll browse a little there, and see if they have anything similar.
Thanks for posting!
