This bus is one of 152 similar vehicles operated by Strathclyde PTE, Strathclyde Buses and First Glasgow between 1975 and 2006. It is entirely Scottish having a chassis assembled at Irvine and a body built at Alexander's in Falkirk.

It was new to Strathclyde PTE in September 1983 as fleet number A109 It operated initially from Knightswood Garage but was subsequently transferred to Larkfield Garage where it spent much of its life on south-side services including 12, 31, 37, 44 & 59.

It returned to Knightswood Garage around 2001 as one of a batch of similar vehicles fitted with seat belts for school contract services in East Dunbartonshire.

A109 was renumbered 31213 by First Group in 2003 and was reallocated to Scotstoun Depot in 2005 when Knightswood was closed. It was withdrawn from service in June 2006 and secured for preservation, arriving at Bridgeton on 28th July 2006.

It is one of the few Glasgow Ailsas to have had three different fleet liveries:

. Original orange / black
. All red
. First Group "Barbie 1" or "Willowleaf"

Initial work has seen the removal of all First Group logos etc and the advert frames on the nearside/ rear together with repairs to the battery box which was corroded, which caused the bus to be withdrawn from service slightly earlier than intended.

It is planned to restore the bus to its original Strathclyde orange / black livery once it has obtained an MoT.
