If you ask me, something doesn't seem quite right - especially without any picture evidence.
Obviously, with just the signature, that would seem to indicate its a US made guitar but then the Serial Number doesn't make sense. Assuming one of the 7 numbers is a year indicator (usually the first so a guitar made in 06??) the rest of the numbers seem too high 714185 when we are are not quite up to 300000 yet. An SE would have the SE on the headstock and have a letter on the back to indicate the year - as well as the made in/by... statement.
Maybe with photo's, it could provide answers and/or information about your guitar but based on just the information provided, something doesn't seem quite right to me...
