Peter and Jane Coulthard started up their transport business in Kirkcudbright in south west Scotland in 1916, naming it after their second son Charles Hayton Coulthard. Five generations later, the family firm is now run by descendant Duncan Jnr and his two sons James and Murray.

The three trucks in the set celebrate the history and success of the company, which now operates over 100 trucks across the UK but mainly from its modern base in Ecclefechan.
First up is an ERF LV tractor unit and flatbed trailer. Bought in 2012, Duncan Jnr gave it a period livery representing the company's affiliation with ERF trucks which dates back to the 1970s-1980s. He named it 'Joyce's Pride' in honour of his mother. It is registered TMJ 9795K and is decorated in red with white roof and gold coachlines to the cab unit.
Second comes the Scania R450 Topline tractor unit and curtainside trailer, registered WU64 BUF and named 'Fiona's Pride.' This truck represents the vehicle which entered company service in 2014 and is also decorated predominantly in red with the special tartan banding which Coulthards first introduced in the early 1970s.

Finally, the third model is a Volvo FH500 Globetrotter XL tractor unit with walking floor trailer, registered WA15 CYL, representing one of the latest vehicles to join the fleet and named 'Hazel's Pride'. Also wearing its tartan bands, the cab is painted red with a white trailer unit and a wealth of company graphics to all sides.

The set is presented in special 100th Anniversary packaging comprising a decorated sleeve over an inner presentation box with accompanying legend detailing the company history.
