F.J. Thornton & Co. Ltd. Weighing Machine Manufacturers, 111 Fazeley Street Birmingham, 2014 • Now for a few interesting commercial rooflines (a niche within a niche, if you will). I came across this zig-zaggy works on a Pevsner-guided walk around Brum’s fascinating Digbeth area. It later housed a branch of the engineering firm ThyssenKrupp, but currently appears empty.
