Here is a picture with headstamp on 8x50R Lebel case. Manufacturer (EDB) is Société anonyme des Etablissements Delaunay-Belleville, Saint-Denis sur Seine, France.
I have a problem with identification of metall supplier with code M of this case. My available sources give two variants:
- Compagnie générale d’éléctricité, Etablissement Mouchel, Tillières-sur-Avre (Eure)
- S.A. Сuivre & Alliage à Ham (Somme)
Which variant is correct? and
What was the correct name of S.A. Сuivre & Alliage à Ham (somme), because I was not able to find info about this company?
Thanks for help
