Definitely a M3 holster - like some dudes already mentioned ...   and - like @thorin6 mentioned the male-piece of the push-button on the lower portion of the holster is broken pretty often so check for it first

This is the only pre-Civil War photograph that I have ever seen depicting a mounted National Lancers trooper equipped with his lance. The photo must have been taken prior to 1855 as in 1854 the Lancers traded in the Model 1833 Dragoon saber he is wearing for Model 1840 sabers.

Hey Elizabeth, this is obviously a couple years late but I see your second question of where these knifes were worn/carried wasn’t quite answered fully or correctly although I’m sure you know by now. But I’d like to post this for anyone else who stumbles across this thread as it really isn’t common knowledge on when and where these raider stilettos were carried. It took me a few years of collecting these with provenance to really narrow this down for certain.    The raider stilettos started being issued in late 1942 and by the time the 3rd and 4th Raider Bn’s were being formed from Sept-Dec 42 they were standard issue to the recruits. I even have a letter of provenance from one of my Co “D” 4th Bn vets stating when, where and by who he was issued his. His by his company commander William Flake in December 1942 at tent camp #4 at Camp Pendleton. The 1st and 2nd raiders did not receive their stilettos until after Guadalcanal I’m quite certain or atleast I have not been able to find any proof of it. Either way the first time these stilettos were carried into “Combat” was with the 3rd raider Bn onto Guadalcanal in Feb 1943 before they went to Pavuvu, and the 4th raiders at the same time as they did small single squad/platoon submarine raids in the area. From there the stilettos were carried by all the Bn’s onto islands like Pavuvu, Vanguna, New Georgia, Puruata, Bougainville etc and from there on out wherever the raider vets served with their units they were transferred to. Many went onto serve on islands like Guam, Iwo Jima and Okinawa but a few were transferred to other units that served elsewhere.

Actually made by J. K. Davidson  for the collector market.   George Studley did not make medals, he only sold them to Vets and Collectors.   Bill

I will reply to you by PM later this morning.   Bill

Nowadays I feel I only ever see the one with the stem, I rarely ever see the circle one

Interesting list, Gerard, thanks for posting.  Also an interesting concept:  you are not listing actual ammo boxes, cans, packing boxes (crates) but you are closer to listing the contents of containers.  But whatever, please include me as a "fan" of ammunition containers of all types.

In May of 2021 Daniel Ellsberg leaked another classified document he had. Its the Rand paper on the Taiwan straights. This is the Rand report:    https://archive.org/details/The1958TaiwanStraitsCrisisADocumentedHistory_201712 This is a declassified US report on air operations for the 2nd Taiwan Straight incident 1958: https://nsarchive.gwu.edu/document/21083-doc-10-taiwan-1958      This is what  Ellsberg said about that document "I consulted with my friend Morton Halperin when he began the research for this study, I believe, in 1963. Having participated myself in the Cuban Missile Crisis a few months earlier, I spent most of 1963 and the first half of 1964 doing research on nuclear crises at the RAND corporation in Santa Monica, California, for which Halperin was a consultant. When I joined the Defense Department as a full time employee in August 1964, as special assistant to the assistant secretary of defence for international security affairs (ISA), my purpose was really to pursue my investigation of this subject, in the hopes of reducing the chance of nuclear war in the future. When Halperin completed his study at the end of 1966, My draft notes on the offshore islands crisis of 1963 were a product of my consultation with Halperin in February 63. In the mid 60s the crisis over Quemoy and Matsu, Offshore Islands in the Taiwan States, which is variously described as the (Offshore Islands) (OSI) Crisis, the Quemoy Crisis, or in the title of Halperin’s study the 1958 Taiwan Straits crisis- was not generally perceived as having been a nuclear crisis, despite the fears expressed publicly by politicians and commentators that it could possibly have erupted into nuclear war. What Halperin discovered in his classified (Top Secret) study, was that the nuclear dimensions of this confrontation were taken very seriously by the Eisenhower administration, and in particular the military advisers and commanders involved. Indeed, Christian Herder, who succeeded John Foster Dulles as secretary of state, was reported to have said later, “The Cuban Missile Crisis is often described as the first serious nuclear crisis, those of us who lived through the Quemoy crisis definitely regarded that as the first serious nuclear crisis.” The reasons for this will be obvious every few pages of this study. -Daniel Ellsberg"

. I have always been interested in animals in military service, and found photos of these metal canisters on another thread on the forum, I have NEVER encountered any details of these being officially manufactured for pigeon use either British or American    However looking at the style of the cans it appears to me that they are converted British army biscuit containers, I could be wrong but it's worth more investigation.              Norman D.
