Well its says on the fuselage it is a Buccaneer, so who am I to argue differently? There seemed to be only two LA-4-200 registered in Indonesia for a while, PK-SAR (CofA revoked years ago) and PK-SMR (deregistered in 2018). The latter seems a good candidate?

This is painted more or less as Zimmermanns Bölkow of aerial demonstration fame, but is an unknown civil NBo105. Its plate was removed and no cockpit radio call plate was visible either. Any offers?

Painted to represent a TNI-AU presidential aircraft, but the construction number plate revealed 1275, dated 6-74, so it is the former PK-PEN. Also, it held a plate marked RO78 dated 10-82. Presumably the conversion date to SA330J and likely done by Brasov in Romania.
