Gary Cunningham's, U.S. Knife Bayonets and Scabbards (the yellow version) is a great start, but it is out of print and very pricey. Military Knives A Reference Book, is a good collection of military knife articles from Knife World magazine. Many written by Frank Trzaska. U.S. Knives, Bayonets and Machetes Book III, by M. H. Cole, a must. Might be out of print, but it is a very useful reference. Knives of the U.S. Military World War II, by Michael W. Silvey, not a lot of text but great pictures.    These will get you started. If you want to get in depth, there are books on specific models of bayonets out there. If you have not been to Frank Trzaska's website usmilitaryknives.com, it is a great resource. Lots of info, you can spend days reading there. Highly recommended.

My Uncle served in Battalion 1, 213 c.a.a.a. in Itay in W.W. 2 He was killed in action on March 9th 1944 in Italy. 

Book 1 and 2 by Bill Walters , Silveys books , and Cole's 3 & 4 . A good place to start 

Ebay Item no. 326596194238. Buckle identified to Ship's Cook 2nd Class William Butynski (1914-1948). He arrived on the P.I. in July 1945 after spending time aboard the USS Migrant and USS Gallant

Within the last year I have begun studying and collecting US WW2 edged weapons. I have learned a lot from online research but would love to have specific books or texts dedicated to US edged weapons that I could refer to in future use. What are some recommendations from the veteran collectors and enthusiasts on this forum? Thanks. 

That oval does not show up in the Stein book

Patrick is correct as ever.     Wauwilermoos  was indeed a miltary prison. Airmen who tried to escape or broke rules were sent there. Conditions were harsh : cold and dirty cells , insufficient food , isolation and abuse. But  most of the 1742 aircrew who ended up in Switzerland  were sent to relatively decent camps like those in Davos or Adelboden where  conditions were similar to civlian internment : decent housing , organized activities and even a bit of freedom of movement.     Dating aviation badges manufactured by Huguenin is not easy. The company went bankrupt in 2022 and permanently closed its doors . A large part of the tooling , dies and stamples were acquired by the "musée d'art et d'histoire de Neuchatel ". Unfortunately to this day , in spite of the curators'  efforts  nothing related to US aviation wings has surfaced. Anyway , it seems that  production was limited as these Swiss made wings are rarely found , making them desirable items.      

Sorry if this is a bit blurry. The 361st Special Service Engineer Regiment participated in campaign 34 during ww2 witch would be the Italian and North Africa Campaign. 

Thank you for the feedbacks ! So it would be a Navy N-4 jacket with button tabs to the wrists and no USN stamp ? What about the brass 'Talon' branded zipper shape ? I thought it would be with bell shaped puller, typical of those found on US made military jackets of the 1940s... Could it be anything else than ww2 era ? Thanks. P.A

Yes,  cool ish water would be best, room temperature at hottest
