Yes, this is complex, but here's my understanding...
German (Weihrauch)-manufactured, Beeman-branded air rifles are sold by Pyramyd. I believe that another company actually owns the rights to the name, however.
Chinese-manufactured Beeman-branded products are manufactured by Shanghai Airgun Company. They also own the "Industry Brand" and "Marksman" trade names.
Shanghai Airguns is a legitimate user of the Beeman brand. I can't remember if they are the actual owners and license it out to the other company for use on the German (Weihrauch-manufactured) guns, or if it's the other way round.
All this happened many years ago.
