What’s interesting to me is NrTrade wasn’t the manufacturer — they were simply an importer. The manufacturer actually produced them until 2012, though they became significantly less common as NrTrade was their main importer and with them gone they only got orders of about 1000 units. AFAIK they started production in 1998, and the manufacturer still makes other famiclones. All SJIIIs have a date on the PCB, so if you have one you can open it up and see the exact date it was produced!
