An extra development which came on Veloretrocourse forum
https://veloretrocourse.proboards.com/
I had said
"
The VITA chain was produced by a belgian brand called CPM, from the initial of their owners, Mr P&M Charbonnier.
It is not well known but in Belgium, we have had a very large cycling industry, mainly derived from the guns manufacturers and the related companies.
CPM commercialized (I cannot testify that they produced some or all of the followings) the VITA products, including chains, derailleurs, lamps and dynamos; they also sold the Hermesse cranks & chainring (for these I can testify that they were made in Liege by the Hermesse brothers); Duraleau rims and Selecta saddles and brakes.
"
Here a picture of the "group"
While this was published some times ago, now this captured the attention of another VRC member who demonstrated that the Vita products, while made in flanders, where actually produced on the other side of the borders.
A part of Flanders is included in the north of France.
This clarified why products from other companies are included on the "group" picture.
So Vita were produced 10 km left from the belgian-french border in the Hazebrouck city.
(the name is written to sound right in french. In Dutch it should be Hazenbroek. The sound would be written Hazebrook in english)
