Probably the most comprehensive collection of scales and weights in the UK used to
be the museum at the Avery Weigh-Tronix headquarters (Soho Foundry, Birmingham).
In addition to showcasing Avery products from across the history of this once-great
firm the collection also presented the art of weighing and scale-making in all its
facets, uniquely located at one of the centres of the industrial revolution.
Sadly this museum is now defunct. As of mid-2015 it is not clear what will become
of the collection.
These pictures give a quick overview of how it looked in around 2002/3.
