Apart from the obvious bargain price, all is in the details.
As far as I can see from the small pics:
Pin is incorrect,
Small pliers are incorrect,
Large pliers is incorrect
Small red screwdriver is incorrect.
I can't comment with confidence on the rest, as the pics are too Small. I don't do Facebook...
Anyway, the tray alone looks very nice, and that would already cover most of 280 usd asked.
Also the 3ring and 3open spanners seem to be correct, and quite rustfree. those alone fetch >150 usd if sold separately.
