I'm collecting material to make some different military 767´s for the upcomming FAIB model.

Can any of you recognize what it is?
The image is on the tail of a Brazilian Air Force Boeing 767 (reg. C-767 2900)
Can see it might are some hands with swords?
All help will be very grateful and appreciated

Or if some one perpaps have a very good close up picture i high resolution..?
Cheers
