Appears to be complete. Machined case with slight wear. Brand stamp to base is faded from usage. The Austrian brand "Imco" are well-known for this design and mechanism. Needs flint and fuel.
We currently have a life-long collection of lighters dating from the 1930's to the 1970's for sale. The condition of these lighters varies from fair to very good. I have photographed and described them as accurately as possible and I do mention obvious faults in the description.
Kindly note that I am no expert so please study the images above and descriptions carefully to assess condition, completeness and authenticity. The lighters are sold as untested and as is.
