The misrepresentation (if any) was probably Cabelas and not the mfr.
That being said, if it said "stainless" and not "stainless steel" then they probably did not misrepresent the product as much as not accurately describe it. That could have been deliberate but I kind of doubt it.
The real test is whether or not they would give you a refund if you told them that it was not stainless steel and that their catalog is misleading.
