In bygone days it was common for bus companies to operate a parcel post or delivery, often providing a supplementary system to the Royal Mail in rural areas. The Bala Motor Traction Co was no exception, running buses across Mid-Wales to the coast and back. The owner and operator was Obediah Griffiths-Jones, well known in the town as a old fuss pot.

Aside from insisting on absolute punctuality of his small fleet of single-deckers, he had parcel labels printed colour coded for each class of goods, a range of values as they were priced by size, and latterly having supplies printed for all conceivable goods.

These are a few of those identified and a small sample are illustrated. The general layout of the labels remained untouched until the end of the service in the 1960s, but specialist collectors go nuts when they find a previously unidentified printing. Those shown below are but a small example of the range of stamps known to exist.
