Watchmaker vises

A reader writes; My grandfather was a watchmaker, and I have the remains of his toolbox. 

Looking online, although there are a good number of Imhoff & Lange tools of all types and also some Hugoniot Tissot, I can't find any information or history of the companies themselves. The world of watchmakers does seem to have disappeared.

Markings are, from the left:

1] IMHOFF & LANGE

2] Pat'd Aug. 10 1875

3] [no marks]

4] [lion symbol] L.HUGONIOT TISSOT, The L stands for Lucien

5] [small five armed sunburst symbol]

6] [lion symbol] L.HUGONIOT TISSOT

7] ACIER FON?? [also 'P' in an Ace of Spades border]
