Sir, I'm new here, just because I found something that even you, with all due respect, don't know, I would never have created this prestigious forum to copy things from AI for you, yes, I have the specification and everything fine-tuned from AI, but the original of this piece is next to it... and if you want proof, I have no problem filming you all the insignia and the shirt as you wish... and I'm sorry that someone can say this, to someone, when you know how much we value the liberation of your Army of Pilsen....  

The back of the two Chief Engineer collar pins are quite similar so I am only showing the one that matches the hat badge.  The collar pins have different propeller designs.

Hello everyone, please, I don't need anyone to dishonor me after my first login, if I got this artifact, I'm writing, it's a fact and that I worked on it all week, that's also true, if someone doesn't even know what I actually have, I'm sorry, I wrote to this forum to find out more, I'll send the shirt as a gift to Wright Paterson, I have no problem with that... and I apologize for my English, but the facts are given and he has the shirt with him... nothing more, nothing less

"Sir, I am not a scientist. I am just someone who found this artifact during the Liberation Festival in Pilsen. And if my English bothers you—yes, I have to use a translator because I am no longer as fluent as I used to be. But I know for certain what I have found and what I have discovered after a week of research and consultations. I stand behind my findings."

I’m not sure how you reached your conclusions (AI gone wild?), but the shirt pictured is a very common USAF private purchase officer’s shirt with little or no collector value.  

The blade profile of the M1905/06 Experimental is very close to that of the M1902, so some M1902 scabbards do fit.  I don't think the M1905/06 was in service long enough for this to have happened officially, though, and I'm unaware of any period photos showing this being done.   The scabbards are notoriously fragile and many sabers were likely sold off either without scabbards or with the scabbards in poor condition.  Personal opinion, the M1905/06 sabers we have today with M1902 scabbards were mated together after the sabers saw active service.

I picked up this Navy crackerjack at an antique store while visiting family and paid $10 for it because it struck me as unusual. I have never come across a U.S. Marine Corps division patch on a Navy uniform, so I am hoping someone here can shed some light on it. The patch is machine sewn and sits evenly aligned with the shoulder seam and makes me question whether it was added later or could have some legitimate context such as a corpsman or attached personnel. I'm a bit skeptical that someone would go through the effort of adding a patch in this manner just to sell it unlabeled for $10 in an antique shop among team jerseys and tank tops. The uniform itself does not have much in the way of identification, just the last name “BIRCH.” Any insight, opinions, or comparable examples would be appreciated. I could be wrong in my assumption; this is just pretty weird. 

You should be dead chuffed at how that's looking Ken.  So will it be screen down when finished ? Kevin

Thanks very much!
