If we look at signature on English pocket watches from the C19th, a top of the head estimate (error + or - 4 -10%) - 60% retailers, 35% watch finishers, & 5% first owners. So my question is ...
For the majority of watches sold in the various countries of Europe during the C19th, what do you estimate the equivalent figures to be?
In the UK we have trade directories that have long lists of watch and clock makers, many we now believe were retailers who may have repaired watches, but had very little to do with their finishing and definitely did not manufacture watches. What was the situation in Switzerland, France, Germany, Holland, Sweden ....
To bring it back to this post - is it possible, even likely, that Leduc of Troyes was not solely a 'watchmaker' ?
Exhibition of Troyes 1860
We can only criticize the mechanical sewing machines exhibited by MM. Callebault, from Paris; Mayer, Leduc, de Troyes, and Duvivier: it is costing too much for their adoption to be general.
Mr. Leduc (from Troyes), who opened a sewing workshop in the annex, mainly deals with circular knitting. The unwinding pliers are a happy idea. Mr. Duvivier's shuttle machine can be applied to lingerie as well as to drapery.
