Hi, I got a Bell & Howard 2143 XL for christmas, and for all I searched, I cant really figure out what film to use. I know it is 8mm, but, as this is my first film recorder, I dont really understand any of the labeling on them. The reason I came to this part of the forum is I saw another post on this recorder, but it didnt really didnt help me much. Thanks a bunch for any help!
