Le Coq is a French safety razor with one hard statement behind it and nothing else. No dating table, no serial range and no code were found; the only fixed point is the country mark, and the country mark is a lower bound rather than a date.
Le Coq belongs to the French safety-razor school, and the sources that were checked carry no stamp table, no code table and no list of model years for it. The one dated statement that survives is the marking requirement of 1891.
Only to a lower bound. There is no code and no serial table; the country mark France on the razor means it is no earlier than 1 March 1891, and nothing in the sources narrows it further.
