I doubt lung cancer was much of a concern given your chances of survival as an infantryman back in WW2.
Have always been drawn to those early WW2 years of 1939 & 40 when Britain and the Commonwealth stood largely alone against the dreaded Hun......
Do really like those early K&C Brits Duke, you've produced an excellent display mate.
My own grandfather was in the NZ army during WW2, but never served overseas. He did make many friends in the 1st Marine division when they were briefly based here in NZ and before their deployment to Guadalcanal.
He kept a notebook with all their address's and contact details in the US, however later learned most were killed on Guadalcanal which according to my grand-mother affected him deeply....he never spoke of the war to me, mind you I've found over the years most veterans never do.
I still have several treasured 'Marine' souvenirs including a water bottle and bayonet.
