HRS:
Good morning Robert,
Dont see many of the Olympic cab ERF, about 1997, EC model ■■ Sold a few but they were a bit dear compared to the competition.
Any thoughts, Harvey
Still a few working, Harvey! Trouble is, even the later ones are long in the tooth now at over 20 years old. And twin-splitter drivers are not as common as they were. Plenty in Africa though!
