Ive tried in the past and failed, my sn start 83-xxxxx and I know its an 83, and made in Japan, but thats as far as I could get, was told they diddnt keep good track of the sn's, Good luck in your detective work
Yep...there was a 3-4 year span where tama put the year first 82-xxxxx, 83-xxxx, etc. Beyond those years, you can still determine approximate dates, but must use several clues to work it out. Superstars had limited runs in certain colors, sizes and hardware bits. So, usually, based upon color, sizes and mounts you can pin it down fairly close. Post some pics that show the mounts, badges and drum sizes and Id be happy to help you out.
