The story
Ullman and Katz set up their toy-manufacturing business in Stimpson Avenue, between Abington Avenue and Wellingborough Road in Northampton, with their company registered on 31 August 1932. They initially produced very similar tinplate toys to those being made in Germany. Within six years the Northampton factory was said to have 600 employees, and from 1944 Katz was the managing director.
During the Second World War the factory manufactured not only munitions but also a cooking stove for troops posted in tropical jungle environments. The Northampton factory moved to a large site, originally used as a boot factory, in Northampton at the corner of Spencer Bridge Road and Harlestone Road, later occupied by Aldi and Iceland supermarkets.
