I'm not sure why you think it cross references to so many different manufactures. For example I believe the only Hawthorne Colt furnished to Wards was the Colteer ( .22 ), no pump shotguns, could be wrong. I believe your shotgun is an import made by Manufrance ( your La Salle ) If may have been imported by others but that is no identification. The new H&R 440 is imported from China ( or was ) and I believe the old 440;s were US made. If Manufrance, then you very well have a hard time finding a original barrel for your shotgun. Manufrance has been gone for quite a while. Good luck with your quest.
