I hear ya - I'm not knocking their expertise, I just want to be able to tell the seller when I return them something a bit more detailed than "these wings are iffy per a really knowledgeble fellow, but you don't know him." I'll hunt around in the wings thread some more. Thanks to all!
At the risk of hijacking a thread on nice vintage theater made wings, I will try to add some insight to the discussion why I think these particular wings are fake.
First off, ! suspect that these are sand cast wings.
In general, I would argue that cast wings fall into two broad categories.
1) Crude sand cast wings. As said before, most cast wings are fake--and were likely made in the 80's or so when the interest in wings began to peak. These sand cast were made to fool collectors, use some cheap pot metal, and almost always are sold as either CBI-made wings or POW made wings (especially if the castings were particularly crude). Well before many of the new and excellent reference pieces were published, most people didn't have a real CBI or POW made wing to compare, so it was a relatively easy scam to perpetuate on collectors.
2) Subsequent to that, the casting process got better and some castings are designed to pass off as original die struck wings. Some of the higher end cast wings can be a real chore to identify (some of the fake JR Gaunt wings come to mind).
In both cases above, the fakes are always based on an existing wing that is used to make the casting mold. Be it an AECO wing or an early Amcraft/LGB style wing (as seen in this fake), they are always based on an existing wing of some sort.
It is my experience that the CIB wings were not usually made by the sand cast method (again, we have to speak in generalities here, as I suspect that there are always exceptions). Remember, these people were artisans and craftsmen. Thus, the wings that were made there almost always show a high degree of craftsmanship. These wings were almost always die struck or hand carved/worked (you can see excellent examples of this in this thread).
Finally, while some small minority of wings were likely cast, those were more than likely made using the lost wax method. The model for those wings would not have been made using a generic WWII wing, but likely something carved out of wax by the craftsman. Thus, these wings are of a unique pattern.
One can't know 100% for sure and I could be well off base, but the fact that this wing is a crude sand casting of an existing WWII pattern wing using more modern fittings and the only support for it being a CBI made wing is the presence of 14th AAF patch in the estate.... makes me say :thumbdown:
