Merchant's Quay in Waterford has gone a bit upmarket since this view was taken. This bus was new as Oldham 127 (CBU 127C) and was sold through Paul Sykes (dealer) to Suir Way Bus Service of Passage East in October 1978. Suir Way is a long-established (1928) business that is still going, now spelt Suirway. Their website even features an old coach with an Oldham registration, GBU 5!
This bus survived some time after sale by Suir Way, gradually decaying on the site of O's Coaches of County Limerick.
