I do not own this.
In 1966 (?) with the success of the G.I.jOE Action figure, Hong Kong companies started making knock-off equipment sets to fit the 11.5 inch G.I.jOE and other generic 11.5 inch action figures.
"FIGHTING YANK" is one example of a knock-off company that was created to grab a piece of this profitable market. Although it doesn't indicate on the box, it is obvious this is a MEDIC set.
Set incudes:
Fatigue shirt (green w two chest pockets);
Fatigue pants (green w 2 square back pockets);
Helmet (white w red cross);
First Aid brassard (whote w red cross);
Plasma bottle
Stethoscope (black)
Bandage rolls (white : 1 large , 2 small)
