The United States Coast Guard ordered 25 Smith &Wesson K22 revolvers, in 22LR, with special order fixed sights.  The K22 Outdoorsman was originally produced with a 6" target barrel with target rear sights.  It is believed that less than 30 fixed sight K22 Outdoorsman were produced.     For training purposes, shooting several rounds of 22LR was more cost effective than 38 special.  Using fixed sights for practice also made sense since the standard revolvers in the 1930's were fixed sight.     This revolver, serial number 650938 was shipped on February 12, 1935 to the United States Coast Guard at Curtis Bay, MD.  

Attached are pictures with patch on vehicles and soldier pointing at the patch on the woman’s coat. 

I sent the patch pictures from Domatan to a 2nd ACR former squadron commander and very active member of the regiment assoc. he sent me vehicle photos with the bottom left design painted on hulls. There is also a hard to see Red Cross woman wearing a coat with army patches and a soldier pointing at what appears to be that patch. So it seems the Regimental Assoc believes the regiment had a patch in WW2 and the one in the 3 patch picture bottom left is the original. Of course there is still debate about the 2nd and 3rd ACR patches in WW2 but as a veteran of both and a 20+ cavalry soldier I find it difficult to believe a unit commander would allow his soldiers not to have their unit  proudly display on the uniform. 

Space race era… science project? Or electronic class project? someone went to great lengths to make it light up…

Looks like he's wearing US Army Communications Command (USACC) DUI's 

Very interesting!   Would you happen to have any context for the photo above? I have never seen it before, but I believe 'RNMC' stands for 'Royal Netherlands Marine Corps' who were fully equipped and trained by the USMC during WW2.   I noticed your hood seems to be lacking the holes for the spare tire mounting bracket, is there any sign they are filled in?    

I have seen this photo printed in pre-Photoshop/AI books so unless it has been altered since I think it's original.    

I wonder if that isn't something created using photo shop or similar. Having done a lot of heavy load crane work on site when building 70 ton furnaces made up of all sorts of shapes and sizes of steel the cables don't look right to me. The way it's rigged with only one rear cable would mean that jeep would be out of balance even more so with the driver sat on the left hand side. Doesn't look correct to me,

It's amazing to me how one can look at something multiple times before noticing something.  This evening,  while perusing the posts on this thread again, a realization just kinda just jumped out and slapped me.   The old "tarnished silver appearing" fancy AMC device in post 47 is now identified as a collar device.  If you look at the 1922 pics in post 57, you can see the device (not clearly) on the right side (wearer's right) of the collar on the white shirt and also on the other cadet in the khaki shirt.
