"The older Fernandes guitars do have serial numbers on occasion, and can be found on the neck plates of the Revival
series Stratocasters and Telecasters, but otherwise, Burny and Fernandes didn’t often use serial numbers. Dating a
Burny or Fernandes can be loosely done by looking at the truss rod cover. The Gibson bell-shaped covers are found on
1970’s to early 1980’s models. The bell-shape cover with a thin white band and ridges sticking out from the side are found
on mid-1980s to early 1990’s models. These old “lawsuit” style models are very rare to find nowadays, and are highly
collectible. Prices even in Japan are triple what they were 5 years ago due to collector interest not only from abroad,
but also from within Japan."

The fact it has a serial number in the right location may mean you have an older one...
