Who can ID this Swiss shoulderpatch?

Couldn't find this in my Ord.49 list of shoulderpatches so I don't know what it is, probably something that came into existence later but I don't have any later files about such patches...

It is for the Territorial Service headquarters and was part of the patches issued in 1949

Objekt: Territorialstäbe / Etat major territorial
Ordonnanz: 1949

Thanks, but are you sure? The shape of the patch indicate it is some sort of specialization insignia, instead of a type of arms or services which are diamondshaped

Yes, you are correct the shields are specialty badges worn on the upper left arm. The diamonds indicate the branch/arm of service and are sewn in pairs on the collars.  The Swiss crosses on orange background are for the general staff/headquarters of the Territorial Service.  

I do not what the requirements were to earn the general staff qualification.  I grew up in Switzerland and was drafted in the Swiss Army when I was 19.  That was a lifetime ago but even back then there were way too many patches in my opinion.  Anyway hope this helps.

Below are a couple pictures I found on the Pinex militaria on-line store.  You can find more details and a lot of other Swiss patches at the following webpages:

Also found a 1950 edition of the 1949 Ordnance.  It included a page on the Territorial Service patches.  

Thanks! This fills a gap in the partial 1950 documentation that I have

Here is a link from the Swiss Army museum with a lot of documentation on the different Swiss uniform and insignia manuals.

Aside from personal equipment, I don't collect Swiss stuff, but that museum page certainly has a wealth of useful information.

Thanks for that, that is an amazing page, I've now saved so many files from there already, and gained some nice insights about how to pack my 90's equipment together for when I take photos of it!

Glad you enjoyed it. There is also a link where you can buy quite a few items.
