Erich Koschyk, Yergen’s son, has established a Type 4 parts and service business out of his father’s shop. He specializes in locating parts and bought a number of 411s and 412s from salvage yards that are used as parts sources. There are plans to start reproducing some items as well. The best way to reach Erich directly is by using email.
