Scottish Buildings Series Tenement Buildings Collection Auld Reid Stane Closie Unit Three Flairs Howe-Frontit/ Old Red Stone Tenement Unit Three Storeys Hollow Fronted.
This is the variant for use with the shopfronts: each unit takes two of the 22ft shopfronts (all start with SBS SF22 xxx) with a door filler (SBS TBC ARS SFDF) between. The screenshot should explain how they go together - there are two hollow units, so four shopfronts and two door fillers visible.
As usual with my sets, you'll need extras to complete the model: definitely lums/chimneys and very likely the Ootside/external Stair, probably the defining characteristic of an older backie.
