Very interesting, I also purchased one of Fred Braemer’s wings at an auction last year. The “Ken” that Fred references was possibly Ken Lazier, a collector that was active in the 70s and apparently claimed he ran a museum and requested and obtained items from high profile veterans for his “museum.”    You can find my post from when I acquired them on this forum.  Don’t know how to link the post.     

Going to assume this is post Spanish American War…Any ideas 

These are Pocket Patches, these being a cloth copy of a unit's metal unit crest, these worn on the left pocket of fatigue shirts and field jackets in the 50s trough the 60s by units that had them. Fashion fell out basically by mid 70s, with some exceptions.   These will be for the 137th Infantry Regiment and worn by either the 1st and or 2nd Battalions 137th Infantry of the 69th Infantry Brigade (Separate).   All you PPs are good period ones, the lack of rear bobbin thread is merely  a maker variation.   Here's one from around 1968-70.full color ones still being worn despite the introduction of subdues insignia.

Great group and well researched!

Wow, good find!  That is awesome.  I probably would have mistaken it for a military school beret.

Thanks Tonomachi. I didn’t think they were sewn on wings because they didn’t match the pictures available of that type but I just couldn’t see what they really were in my head! Thanks again!

Below is a link to a prior post by mslurvey which provides a list of manufacturers of USA metal insignia along with post 1950's alpha numeric manufacturing codes.  This link may help you identify the manufacturer of some of your ribbon bars.               

That is some cool information.   I have nothing to do with the auction, but for prosperity's sake, here is the link   https://www.auctionninja.com/foss-appraisal-service/product/item-3807642.html

That is some cool information.    

You mean Allen screws?
