I am looking for age of Sterling Ray34 that I purchased

I purchased a Sterling Ray34 on-line from Music Go Round, in California. It is a honeyburst finish. The serial number is SR15675. I would like to know the “born on” date of this instrument. I purchased it for what I consider to be a very reasonable price. Since it was used, I had expected it to show some signs of use but it was in mint, perfect condition.

Thanks,

Kenyon
