Bought a map of Glasgow NE 1895 (also includes same area 1858) from Alan Godfrey
There is an interesting article, with this map, by Dr Gilbert T Bell where he states that,
Arrol's Bridge and Roof Co, Germiston, "besides the obvious products, produced the giant Ferris Wheels which were erected in Earls' Court, Blackpool and Vienna"
Suddenly listening to the "Harry Lime" theme takes on a new resonance.
