You asked:  Can anyone help me determine when he enlisted, if he was in WWIi, if so which engagements, when he received his purple heart, and how much of the Korean conflict he was in. Finally, his involvement and duration in the Vietnam conflict and when he retired from service (I believe he was in for 27 yrs).   Arthur G Stansbury enlisted in the Marine Corps on 11 Oct 1946.  As far as WW2 he would've been in any engagements against the enemy as the surrender of Japan was signed 2 Sep 1945.  A soldier could be considered a WWII veteran if they served up to July 24, 1947.  He was of course in the Marine Corps during the entirety of the Korean War but I'm unsure exactly how much of his time was spent overseas engaging in military action in Korea.  I did find any information about how or when he would've received his Purple Heart.  There was no information I could find regarding his involvement during the Vietnam War or when he retired from service in the Marine Corps.  Ancestry U.S. Marine Corps records do not go past 1958.  I could find no newspaper articles regarding his military service other than his obituary.  If you really want to get detailed military history on him you'd need to contact one of the research sites like GoldenArrowResearch.com and they would be able to get you more detailed records on Arthur.   Here's what I was able to find.                               Ancestry - Arthur Gerald Stansbury.pdf Birth Certificate - Arthur G Stansbury.pdf

So, I'm finally getting into (human-powered) WW2 two-wheelers.  My latest project, the beginnings of a Mk.V bicycle.    Found the original early-war brown paint under several layers of late-/post-war Olive Drab.  It does have an ABL stamp, so it was used by the Belgian Army in the 1950s/60s. The hunt is on for parts and accessories to turn it into a proper WW2-spec Mk.V.  What have I gotten myself into this time?!  😄 And to keep this post US Militaria related: US soldiers riding British (Mk.V*) bicycles along the French Riviera (as reproduced on a number of bicycle related pages, including Johan's )   

At least they bring them to the VFW disposal bin and not the trash although sadly I'm sure many do end up in the trash, especially regular flags.

Rank wasn’t initially included on USN officer overcoats at the beginning of the war, only starting in 1863 for *Captains, Commanders, Lt Commanders, and Lieutenants that changed (and going forward into the 1864 regs) but given combat conditions that wouldn’t have been followed everywhere especially in the brown water navy while underway. See the pics on the initial post. (*Note, Admirals/Commodores/etc had their stars but I’m not going to look up right now exactly what “higher than Captain ranks” were included on the exact date of the collar rank order. It changed too frequently)

Hi guys. I have zero knowledge about Navy uniforms. Is this set WW2 or post war? If WW2……I might keep it for a USMC Corpsman set up.

Spotted this, looks to be of vintage and American made, would be post 1968 when the Super Artillery Branch of 1957 spits into two in 1968, with Field Artillery reverting its traditional Crossed Cannons insignia,  but we haven't the foggiest as to why made and what these would be worn on,

Ha ha ha. Went right over my head.  Got my attention though lol
