As far as I know acc. to what I've read here the sn#470XXX are the European and the #471XXX are the "more coveted" American. No slam there but as I stated earlier I cannot see alot of difference between my 2. Cabela's just had a 4E .410 that was tempting but I have a few too many fires burning now. Try contacting the Firing Line in Colorado. They may have a few left "in the safe" as he stated when I bought one from them a couple years ago... He had a 7E .410 that he offered after he went to see what he had in stock!!!
