Concerning the Sommerda boxlock, number 16 on Erik's link,

Does anyone know the story behind this maker? when was it publicly owned and when was it privatly owned? Is it Correct that Dryse, who apprenticed under Pauly, founded this firm in Sommerda Germany...and the name began to evolve...something like Dryse to Rhienmetall Machinewaren (sp?) and eventually Heckler & Kock?

Is that Sommerda the same bloodline as HK? or have I got that twisted?
