Should get a Harter's pan to be authentic. Harter's is still in business as a mostly non airplane hobbyshop in Belleville, IL. Clarence Idoux had West Side Hobbies, first in East St Louis, then in Belleville, for 52 years. Clarence passed away several years ago. He was very knowledgable and parts for just about any engine you could mention. You can read about him in Charles Mackey's "Pioneers of Control Line Flying" available from PAMPA.
