do (due) to the war on both fronts they had the pin plates made by a manufacture who was not under rzm control,as i understand ges gesch was still in use,
Seeing as this is still relatively fresh in my head, let me help out.
Your assumption that Nadelfabriken were not licensed by the RZM cannot be proven. (although i agree) Of the near 200 M2/ or Metallabzeichenhilfsfabriken, we only know the names of about 30-35.
When it comes to Nadelhersteller we know the names of about 40. Just because none of these 40 names are found amongst the limited numbers of the M2 that we know, is nowhere near enough proof that they, one or two, or those used later on, were not licensed by the RZM. I would guess though, that none were, seeing as it was a mundane item that makers of such would have been supplying to the industry before WW1 right through to this day. I see no need for an RZM license, the same would apply to a Maker and supplier of Enamel powder/granulat, i also see no reason why they would need a special RZM permit, in this case theoretically also an M2 license, to sell powder.. That is just my opinion and is not law, the same as what you are saying can also only be your opinion, and cant be used as the basis for debate on this issue, let alone used to reached any opinion on authenticity.
Regarding purchasing, they were not free, and every sub-contractor or badge maker would have had to purchase them. There are adverts known by makers of badges like Steinhauer and Deumer who advertise Nadelhaken, but this is also no proof that they made them. I would take a guess that amongst the near 190 Licensed M1/ makers, none of them made the attachment.
The abbreviation GES.GESCH is still in use today, 2012
I dont see any problems with the pin plate at all, although i must just add that this form of pin plate was used before the Third Reich, and well after as well. The last plate like this that i pulled off a badge was made around 1980.
I cant comment on your badge, but the pin plate cant even be considered as a point of argument in relationship to this items authenticity, you must use other aspects. What they would be i cant say, because i have never had one, and would not know what to look for.
edit:
The last plate like this that i pulled off a badge was made around 1980.
In fact, the early fake enamel badges made around the start of the 70s also have these pin plates on them
