the “warbird collection series” with picutres of the completed model on the front and side with vertical stripes are reboxed italeris. “real” tamiyas are the ones with box art as opposed to pictures of the completed models
btw, tamiya has been doing this reboxing this for ages. infact, all manufacturers have been doing it for ages.
Hint: Look for “PLASTIC PARTS AND DECALS MADE IN ITALY” on the Tamiya box, usually in the upper right corner. That’s a sure way to tell that it’s an Italeri kit!
