A small side-step full of 'mays' and 'coulds' you could or may not find interesting:
As you wrote your father came from the North of France, and conjecturing your nick bar the first letter is your surname - a Dutch name, meaning 'brewer('s son)' - I assume he may have been from Flemish France, in the present
Région Nord-Pas de Calais. One of the most respected cutlers in this region were, and still are
Maison Leclerq of
Boulogne-sur-Mer, purveyors of fine knives, scissors and razors and all related since 1807. First misreading the stamps for
Lecler Co, Bouloon Manah recently sold
this razor made for them in consignment. Your hone could well have been purchased at this same House.
