The Western SMT (Scottish Motor Traction) depot in Lonsdale Street, Carlisle has been changed into a furnishings store for many years now.  The fairly compact layout makes for a useful large model , with doorways either dide of the front office / enquiry office. This is the largest Kingsway Models kit so far.
The full relief model's footprint is 20" x 12" although a further 6-8" would allow for the width of the street outside.  The garage roof is easily removable allowing for access inside. A good number of vehicles can be accomodated.
Many thanks to Andy for suggesting this model and also for his invaluable help in pointing the way to information.
