Ill take the Sykes Fairbain pattern next to the German M42 helmet. Just send the helmet too they are stupid. Ill deastroy it with my collection of Confederate General statues.
The big flat bladed one looks to be some sort of dive utility knife. Check it for any elctro pencil dates or initials indicating degaussing.
The knife next to the bush knife is a Condor Jungle Bowie. The bush knife is what I was thinking when I said smachet. Not a true smachet, but that style. Anyway, I was obviously wrong.
