A string of N scale Non Air Hoppers
The finished string of the start of hopefully many hoppers stand ready for use behind NSWGR 1803 with matching S truck. The S truck has a bit of brass wire bent in such a way to hold onto the chain link coupling at the end of the 'string' of hoppers.
Microscale letters were used to represent the different colliery letters.
Chain was used to couple the hoppers together permanently and enough slack is left so that a slight gap is allowed between the buffers.
