We made the mistake of having our T210 weighed after we bought it.
It was 150 lbs over the standard empty weight, and that now becomes the
"official" weight for weight and balance purposes.
Hindsight being 20/20, we should have gone off of the aircraft
original documents, and reconstructed the weight and balance from the
log books for equipment installation and removal.

WW Still looking for the gold bars the previous owner hid in our
plane.
(not for the money, I just want the weight back!)
