CJ, I think it is Lajot for your gun. I don't see anything we have uncovered to say it is a Britte action gun. I would think your gun was made in the 1920s. Is there any stamping on the ejectors ? I am thinking that you did post pictures of a Lajot 20 ga. some time ago. That gun was marked N.Lajot Liege on the receiver flats. Are you sure this one is not marked that way ?
