As can be seen from the lower picture, the kit comes as a moulded hopper and two sprues of detailing parts for chassis and main body.
Cleanly moulded, it is a matter of identifying the parts, removing from the sprue, cleaning up and applying adhesive-MEK in this case.
As usual, Paul Furner has supplied an excellent set of instructions and exploded, numbered, views of the components. Several suggestions are made , such as which point to paint the hopper assembly, all helpful if a pigs ear is to be avoided.
I managed to pick up another sheet of original Woodhead Transfer at Westfest, so I should have plenty of options where numbering is concerned.
With various references to articles and books holding information on this piece of rolling stock- it should be easy to find a relative photo.
