.or maybe it was the first in its' parent country ever to have landing gear.
Now there's a thought, but no! I'm guessing that rhey were pneumatic, but again it's not mentioned.
I'm hoping that it's not mis-information, but my reference website (quite well known and often used here) says it was the first use in the country of a certain type of landing-gear!
Edit to say that Reg is on tha right track, but I don't want to ram it home as that would make it too easy!
