Found this verbiage in a 1920 Advert:

"ARMES DE LUXE aux Matres-Armuriers GONDR-MAINWARING
44, rue des Petits-Champs (Av. Opra)
Fusils d. HRISSN-HUSSEY Lof
Superbes armes de LEBEAU-COURALLY"

Unsure of the spelling - GONDR-MAINWARING

Seems August Lebeau was a staple for sourcing by the Paris firearms merchant contingent.

Kind Regards,
