Förester would have in turn placed an order with Heym, or C.Heym who acquired a Gesteck / Parts Kit from Heym with the 3 trigger platform. It is entirely possible that W. Förester ordered an >>in the white<< platform and had his mechanics to complete it. But the typical sourcing line was to send a telegram to a mechanic or compagnie in Suhl, have them make & the put the retailer's name on it, and put it on the next Ox Cart to Berlin.
