Change here for Campbeltown...

I finally got the windscreens in the new model coach and here it is - photographed from a suitable distance!

In real life, in the 70's a Western SMT coach liveried like the black and white one above would come down to Ardrishaig from Glasgow and then go on to Tarbert where passengers bound for Campbeltown would change onto a West Coast Motors vehicle.  For only a week in 1970? (still researching this), that I can find proof of, did the Western coach go all the way through.  This was due to restrictive route licensing that was introduced in the 1930 Road Traffic Act, to protect the local 'first on that route' operators from (in this case) Glaswegian predators, MacBraynes and Link Lines.
