The top antenna is not centered on the fuselage, but noticeably offset to the port side. See photos. 

Pre-assembled airplane model made out of metal with a high level of detail, and produced in limited quantities, which makes it a highly collectible item likely to appreciate in value with time. 1:400 scale means that the airplane model is 400 times smaller than the real aircraft, so they are small airplane models that fit in your palm. Not suitable for children.
