Welp found what the train stands for. Railway Security still curious with the monster LOL right, doesn't look like he's defending it waving it over his head LOL   Unit was big time in Germany during the Post War and Cold War a lot of years, so this UA DI is more then likely German.     1944 to 1948 then 1955 to 1993 https://www.usarmygermany.com/Sont.htm?https&&&www.usarmygermany.com/Units/MilitaryPolice/USAREUR_385thMPBn.htm

Absolutely.  Two-tone, light grey parkerizing (slide vs frame) and that slide stop are definitive late War details.  Very nice!

Their bodies are buried in peace; but their name liveth for evermore. Ecclesiasticus 44:14   Not for fame or reward, not for place or for rank, not lured by ambition or goaded by necessity, but in simple obedience to duty as they understood it. They suffered all, sacrificed all, dared all, and died. Anon.   Poor is the nation that has no heroes, but poorer still is the nation that having heroes, fails to remember and honor them. Marcus Tullius Cicero   Romans 10:9–10   A civilian cemetery about 2 miles from my house understands Memorial Day as well as any.   The last pic is the iconic Camp Pendleton sign on Interstate 5 northbound,  pritnear San Onofre, that's been there for more than 50 years, taken last Friday.      God bless America and our fallen warriors.      

The above crest will be an unauthorized one obviously probably WWII or occupation period, the occupation period being the height of the adoption of unit crest designs by units that during the war after they were formed did not have a unit crest of their own authorized , if we can see the rear of it to really tell.   Here's the duly authorized one for the 385th Military Police Battalion approved in  September 1955.

another. Looks to be Japanese made   

THe ones for water were different on the old metal cans I recall. THey had a different locking cap that sealed and were painted white on th einside. Also had a W mark on them where the fuel had a G and a screw cap.         

Wild unit crest there LOL, wondering what the correlation is with MPs with a a monster, like what an ugly giant, standing in flames holding aloft a train; like he's going to destroy it LOL   Motto vincit qui primum gerit by the way translates The one who wears it first wins., question of course is wears what, what the train is going to be worn around the giants neck like a necklace LOL

Could be a Pattern knife.  These are made by various unnamed folks by copying a common knife and marketing it as a "type."  There are a lot of Pattern knives made after the PAL RH36 out there.

Thank you for sharing this.   The losses from war are sometimes hard to fathom and need to be remembered.    Dan
