Described as
"EXCELLENT. This locomotive has been professionally assembled and painted. (By whom?).
Fitted with an open type motor with fine gearing. There are some light marks.
It is working, but will attention to the valve gear on the left side as on of the parts had come away, but is included.
With a little fettling you will be away".
So not working then!
and
"OO SCALE" is not a scale. (4mm -1ft is the scale).
