Is a Forney 415-C LSA compliant?

A simple search on the FAA website turns up 30 415c,d,e,g models made by Forney with current registrations. See attached.

I did a more extensive search of expired/cancelled registrations, and found 24 more registrations of 415c, cd, d, e, and g models. See second attached.

Unless this is a huge error on the FAA website, I dont understand why these are Forney? Could some owners have derated a 415-G to a C under Forney?

If that were the case, then I dont think these would be LSA compliant, but if they have always been 415C or CD, why are they called Forney?

Perhaps someone knows the answer?

You may be on to something about a "bill of goods", but when I checked with the FAA records, there are dozens of aircraft listed as 415-C, with low serial numbers made in 1946, but manufactured by Forney. Here are just two examples:

N99417
N99558

I find it hard to believe that the FAA has dozens of such entries, but they are there.

I have been looking for a 415-C Ercoupe to fly under sport pilot rules, and have found several 415-C aircraft listed as made by Forney. These Forney aircraft have manufacturing dates of 1946 and serial numbers that are between 37 and 2181, which would date several years before Forney acquired the rights.

Are these 415-C Forneys LSA compliant, or could they Forney F-1 somehow derated to a type 415-C?
