SPW025611 SCOTLAND (1929). Arrol-Aster Car Factory, Heathhall, Dumfries. An oblique aerial photograph taken facing north.

Marked as a Rubber Works on OS Maps circa 1950, it is the former Arrol-Johnston Ltd Car Factory located on the west side of Heathall Aerodrome - a WWII site. According to Canmore - the Scottish Historic Environment Site - "Heathall airfield began life as the Tinwald Downs Farm landing ground of the Arrol Johnston Ltd factory (just to the west), which in the First World War shifted production from motor cars to aeroplane engines, and later in the war, to complete aircraft. The site of Tinwald Downs Farm lay within the footprint of the technical area of the Second World War aerodrome. Fife notes that the landing ground was for the delivery of spare parts by air, rather than the flying out of aeroplanes produced here, and notes the delivery of completed aeroplanes by rail to Renfrew aerodrome" The factory lies to the west of the railway line and station that serves it; so I think we are looking south - not north as advertised.
