I sometimes keep stuff, but of course never munitions. I never dig. I usually consider surface finds fair game, anywhere. It seems to be in hindsight I am a keener collector from my armchair....... Sometimes if one sees something on the ground when one is hot and tired, one has the feeling 'leave it, that the item belongs there'. Not always!
Small collection. Notable Italian para boot sole, goggle rims, possible latch to German field telephone(?)..I leave the rest to you to ID
Shoulder title and flaming grenade gifts from local friends. There is a high salt content in the surface soil in that region, nearly all steel items seem to have long rusted away.
