This is exciting for SWORDies like me.
This looks like a normal boxed Thunderbird 7 / Project SWORD Beetle by Imai.
But it contains the elusive WHITE version of the model!
The usual version is orange as pictured on the box.
I really like this white version and may look out for one in the future.
I think it was released in the 1980's.
I saw this beauty online and saved these pictures.
Have you got one?
