ChiefShotguns,

Their are some common "designs" in hammer doubles from the late 1800s-early 1900s, many made in Belgium. Makes me wonder to what extend makers of these guns were purchasing actions and other parts from a common source -- Sauer? -- and assembling guns having much the same features. For example, the Sauer M2, Husqvarna M52 and some apparently Belgium guild top lever hammer doubles look much like peas from same pod, save for external details and decorations.
