I picked up this CLC made helmet with the liner - both marked 1942.
It came from a family of a Polish soldier from 2nd Corps. His son sold it to me saying that his dad, recreated his wartime helmet for display in 1980s.
It looks almost new on the outside with a coat of varnish and wax on top of the paint.
Anyways, I found it interesting - if any Polish collector is interested - let me know.
