In your earlier post, you mentioned that "not much information is known about this maker" and if anybody had some additional information, please post it.
It was not my intention to be the bearer of bad news, just facts. Sorry if I made you angry. Frankly, a lot is known about this maker.
As I previously indicated,Weyhing brothers manufacturing company is still in business. It has been in business for more than 100 years. Their level of workmanship is arguably second to none. It could be argued that they are one of the bets "small shop" silversmiths involved in insignia making left in the United States. They still do business at 3040 Gratiot Avenue, Detroit, MI 48207, telephone 313-567-0600.
So, to answer your query, that is who made your wing. They certainly made the wing you have. They also certainly made the wing PFrost has as well.
Also, I note Tomamachi confirms that there was at least a dealer with numerous of these wings (about 6) about 10 years ago at a GW show. So that direct observation provides some additional support for the statement these wings were seen in multiple group quanity, a decade or so ago...
I saw the Weyhring jump wings from the batch orders 10 or 15 yeas ago myself, and in my opinion those looked just like yours Robert, but they did not look like PFrost's wing. But Lord only knows how many of that mfg style were Weyhing made and precisly when they were stamped out (probaly stamped out when anyone wanted to pay for some?). But I am aware of an Order being placed, and jump wings being produced by them, in that time frame, a decade or so ago, and some of the people who received the those Weyhing jump wings frequent this forum.
Comparing PFrost's wing photos with yours, the back of your wing looks subtly, or more than subtly, different from the one PFrosy has (his looks a lot different to me, older, with different manufacturing techniques, than yours). Personally, I think your wing was made more recently than your "1950's" contention, but that is a debate neither one of us can prove it, without probably getting direct input from Mr. Weyhing himself (see his photographs, at the link above).. Yours is a lovely wing, I wasn't trying to insult it; it just is what it is.
If you want to think yours was made in the 1950s or 1960s, it would agree that anything is possible.
This company certainly did make insignia, and probably did make jump wings, during World War II. I suppose you could actually call them up and ask them. I haven't done that, but perhaps it would be interesting to see if they still have that information. So, there is a phone number and if you need any more information on your wing, maybe they can help you further research your wing.
I was just trying to let you know there was a bunch of these made fairly recently, and they looked like yours. Again, not trying to insult you or your wing, just share some collector knowledge; sorry, I thought that was what this place was all about...Again, I apologize if I stepped on your sensitve collecting toe.
