ESP 400 series

This is a guitar that I bought second hand in a lifetime opportunity in life. I do not know its origin and the year it was manufactured. If anyone had any idea how to get this information, I appreciate it to let me know As an ESP caught my attention, being a 400 definitely had to be mine, are rare around here and whether I have seen two unoas sale in my country. I've been with her for about four years, it has become my main guitar.
