The firm had its origins in work Twining was doing as a sub-contractor to Bassett-Lowke's.
It specialised in architectural, industrial, and transport models.
Before WW2 it made a number of models for the Queen Mary's Dolls' House, designed by Sir Edwin Lutyens and now at Windsor Castle, stained-glass work (on which Twining was an expert) and astronomical telescopes.
After WW2 the firm made a number of planning models used in the re-development of bomb-damaged cities, also various kinds of power stations and industrial developments.
The firm was never large, usually employing only a handful of craftsmen.
