Rhondda 111 was one of the early withdrawals from the batch and had an unusual fate. It was used a demonstrator by Welsh Metal Industries to show their new body design.
Following that it passed to H. J. Yeomans (Radnorshire Motor Services), which was effectively a "sub-fleet" of Yeomans. Formed due to the threat of Nationalisation in 1948, the Yeomans fleet was split into a number of smaller sections, run by different members of the family. The fleets were re-combined in 1950 when the threat of nationalisation was over and this bus became number 78 in the fleet of Yeoman's Motors, Hereford, as seen here.
After withdrawal it was stripped of its running units and towed to North Wales for use a living van by Yeoman's staff. It was sold in 1952 and became a caravan at Lower Barewood (just south of Pembridge). That would normally result in gradual deterioration as the elements took their toll on the structure, but because Welsh Metal Industries bodies were aluminium-framed it survived in fairly sound condition.
In this condition it was recently rescued for preservation by the Cardiff Transport Preservation Group and is now part of their collection.
