ID On Takayama Serial?

Hi all, hoping some expert on here stumbles on these pictures. Recently traded for a 7’4 Takayama ‘Egg’ board serial #2010. According to the guy I traded with, it is at least 20 years old. Does anybody know anything else about this board? Best guess year it was made? I reached out to the surfboard company a few weeks back but haven’t heard anything. Super stoked to take it out once I get it back from some ding clean up.
