Not sure if this was already common knowledge, but I contacted Fujigen to see if they were still manufacturing any of the SG-body type models and they replied that they have discontinued all SG models with no plans for restarting production.
お問い合わせくださいましたSGボディタイプのモデルにつきましては、NCDCを含め、全て製造を中止しております。また、現時点では、製造を再開する予定はございません。恐れ入りますが、ご了承くださいますようお願い申し上げます。
We have discontinued all SG body type models, including NCDC. In addition, there are no plans to resume production at this time. We apologize for the inconvenience, and thank you for your understanding.
