I have a sako L461 serial no 97578. This was purchased in 1968 , so, I guess no 86302 would be somewhat older.
This link is from Sako's database, and lists older models and dates of production: http://www.sako.fi/pdf/datatables/SakoOldmodelsNumbering.pdfsako classic 270 serial number 654798 how old is it?
Unfortunately, the current owner of SAKO (Beretta) does not publish date of manufacture tables for NEW Sako rifles. Try contacting Beretta Customer Support through their website.
No known published sn data in the US
No "code" involved. You just have to find a source for SAKO serial numbers.
No way to answer since serial number was not provided.
only way to know is to contact SAKO
