This is a 8X50R Lebel datted 1933 with CN headstamp at 9 o’clock and SF - at 3 o’clock.
As per standard French scheme the manufacturer’s code must be at 9 o’clock and metal supplier - at 3 o’clock
This specimen has code CN at 9 o’clock, which different sources make a different ID as:
- Ateliers mécaniques de Normandie, Caen (which is correct, I think) or
- Est Claudinon et Cie, Chambon-Feugerolles
And at 3 o’clock we have SF code, i.e. SFM
Help me please to understand who was supplier and who was manufacturer of this case
