Surely he meant ordered at Osh in 04. Probably got them about 10 weeks later. Late 2004, maybe someone else that ordered their wings along the same time will chime in.
Don't know what, if anything changed since then. I purchased my wings last year and the instructions (insert for manual) are dated 1/20/05. Could have been changes or maybe just correction in the text. Mine appear to be the same as the others I've seen on the web that are older.
