Thanks for the info, I bought it off EMEDALS. I wasn't sure, but now I see the old listing in the archive of their site.

Buckle - made by  Klein & Quenzer, Idar-Oberstein RZM M5/276. I have not seen a buckle marked that way so I Googled RZM M5/276 and found quite a few for sale on line from well known and respected dealers. 

IIRC it was purchased from the Ruptured Duck Militaria, or from EMEDALS.. I'm not 100% sure

Looks like a nice grouping of things- The early dagger with the motto is nice, and although I have not seen a buckle marked that way before, I can't see any red flags that pop up on it.

Note; All these items were acquired separately. Not a grouping. Any further information, like if you know the what RZM codes mean, or if anything looks suspect. Feel free to comment.   I know at some point I'd like to aquire a hj shooting/marksman badge, and district sleeve triangle too and maybe some other tinnies. I think those would compliment these other items.

6. HJ/BDM Scarf and knot Basic black cotton scarf worn by most male Hitler Youth (HJ) and female League of German Girls (BDM) members around their necks. Secured with a leather knot or woggle. No tags, stamps or markings are present/visible. 7. HJ knife with belt scabbard Standard HJ Knife or "fahrtenmesser" Early type with the motto of the Hitler Youth "Blut und Ehre!" or "Blood and Honor!" etched on the blade. Made by Carl Heidelberg of Solingen. Scabbard leather strap is also marked with "L *symbol* S" stamp. I don't know what this indicates. Probably the Scabbards maker mark?  

Sharing my small collection of Hitler Youth related items. Perhaps members here give me more information on them. - HJ knife, early motto type - HJ/BDM scarf and knot - HJ Armband, "BeVo" type construction - HJ Belt Buckle - HJ Membership badge - HJ proficiency badge - HJ "Jugendfest" 1937 tinnie 1. 1937 "Jugendfest" tinnie   A tinne given to HJ members who attended the "Jugendfest" festival, a scout jamboree-like event for the Hitler youth. As I understand.   2. HJ Proficiency Badge, Sliver grade Awarded to members who passed a series of exams testing their physical fitness, academic knowledge, and ideological purity.  As I understand there were different color grades, but they were awarded based on age rather than how well you scored on the tests? Marked "AD. Schwerdt, Stuttgart 8930" 3. HJ membership badge   The basic Hitler youth membership pin badge. Marked "RZM M1/145" 4. HJ Belt Buckle, standard type Standard HJ uniform belt buckle. Worn by most HJ members. Marked: "RZM M5/276" 5. HJ armband Standard HJ armband or "Kampfbinde". Worn by most members. Mad of cotton, specially its "BeVo" type armband, as I understand. No visible stampings or markings. There's leftover black color threads fabric and pins holding it together. Makes me wonder if this came off a black HJ winter uniform?

mmm, yeah, i read that the leg over embroided version was phased out in mid '42, very soon after it came out and alot of those leg over ones were private purchase. Makes sense for the officers, kinda like a "bullion" version of insignia. interesting Tono, thankyou

It does have a spring loaded trap… thanks Rich fir sharing your knowledge j 

Not made prior to 1945. Not a replica of anything made during the third Reich. The swastika is not original to that dagger but was added to fool inexperienced collectors. Google Ern Solingen dagger.

Early gas tube (Great. Wish mine had ir). Later take down lever. Does it have the spring in the butt trap?  Rich

Thank Rich!
