The Pegasus SSI with the black backing material in your first three photographs does not match the Canadian made Pegasus SSI with the black backing material in the photographs I posted.  The key is not just the black backing material but the details in the embroidery of Pegasus and the rider (Bellerophon).      The "silhouette" of Bellerophon on Pegasus was adopted as the formation SSI for all airborne units in May of 1942.  The official SSI issued to enlisted personnel was the printed SSI.  Officers were not issued the SSI as they had to purchase them with their own funds.  This is where the embroidered version of the printed SSI came from as a number of insignia companies started producing an embroidered version of the official printed SSI for officers.  Officers also had to purchase their uniforms so instead of buying what enlisted personnel were issued they wore fancier tailored uniforms made with better quality material.  Their insignia was also fancier then what was issued to enlisted personnel.  However officers were not the only ones to wear the embroidered SSI as some enlisted personnel also purchased the embroidered version of the printed SSI for their uniforms.      Supposedly a number of these embroidered SSIs differed slightly from the official printed SSI so for the sake of uniformity the authorities made the insignia companies follow the exact design in early 1944.  Two things in particular was the elimination of the leg of the rider and the spear had to be perfectly horizontal.   So you can date some of these SSIs due to these changes.   For instance the above Canadian made SSIs as well as the embroidered SSIs in your first three photographs are all pre 1944 embroidered SSIs as you can make out the entire leg.          

yes, there are many diff ones (shoulder tabs)and yes,  thats what i thought too, RAMC did make sense, But i have done more research and found that patch could be C.A.M.C (canadian army medical corps) as the british had red letters on green, while the canadian had white letters on maroon, also at the bottom of the picture there seems to be a white armband, which could have possibly been a medic armband, so again, the medical part makes sense.   thankyou for all your help guys, great to brainstorm these things together, , going back to my original post, I think that pegasus patch for sale is a canadian version (the store is located in canada) so i may keep looking thanks guys, big help

Trying to determine the he origin of this SKS… AI says it’s a 1956 Sino- Soviet Norinko SKS   can anyone validate this? very clean …

Welcome to the WMF, Colt!

Awesome pics of different Pegasus patches, thanks for sharing!   "A.M.C." - Not my field of expertise, but the dot before the "A" makes me believe that it could be "R.A.M.C." Royal Army Medical Corps.

Oh, for sure i want to know what the backmark means. But I do know military collecting message boards don't love button talk too much, and that's pretty much all I post about. 

Ahh ok. So the embroidered versions have the black backing. I’m recently back from a Normandy trip and took many photos of Pegasus patches in museums. Now I wish I documented better, but there were quite a few printed versions and some embroided.  the fist 3 pics show the black backing, but the rest are printed, and I think from memory a mix of British and Canadian.  so in conclusion maybe the initial patch I posted then could indeed be a 1944- onwards, Canadian patch and not a British version.  thankyou Tonomachi for your info, I couldn’t find that reference anywhere so very helpful.  here are the pics below of various Pegasus patches I saw at the Pegasus bridge museum.    Also could anyone tell me what the “A.M.C” on the shoulder patch below would stand for as I cannot remember who’s jacket this belonged to, Canadian or British?   thanks guys, really would love to purchase a British ww2 version but am thinking to be safe, maybe an embroided one is the way to go as it’s easier to identify from a Canadian one.  Also I’m now wondering if the British versions are bluer while the Canadian versions are whiter horses🤷‍♂️is this something anyone else has a opinion on?

I have not seen the "MSG" stamp before, but the white NDSAP marking is usually seen in the Political Leader Armbands (usually with a directional arrow and "Ober" so they are worn correctly) could be a pre RZM maker marking. But I would say a Political leader vs SA armband.

Looks like the police service emblem is glued on. 

I have never come across a "printed" Canadian made Pegasus SSI with a black backing but I do have information about embroidered Canadian made Pegasus SSIs made during WW2.  In the first and second picture they appear to have black backing material which is where your information concerning "black backing" probably came from.    

You helmet with the lugs for the chinstrap is German, either model 1916 or 1917.  (actually there was never an actual model 17, that's a collector term designating the metal liner band from the earlier leather liner band. ) The other helmet is Austrian, and takes a different kind of strap.  The strap on the Austria is certainly not original to the helmet.  Almost looks like nylon.  Austrian straps were mostly a canvas strap with leather fittings.    Steve  

It's perfectly correct, but enhanced if you had, in this instance. said you wanted to know what the IR meant.  You posed no question.  Now, all that being said, I don't know what IR means other than some manufacturer.   Good luck with you quest. Steve
