I think King Concept is the importer for Hewes reels. Anyway, when you order King Concept, you get Hewes. Likewise, Adorama's "heavy duty" reels are Hewes.(posted 8795 days ago)The 120 version is similar to the 35mm in that once you've caught the film, it has already started loading into the spiral. The 120 reels use a larger clip than everyone else that is mounted backwards, so you're not trying to stick the film on top of your finger.
The Hewes systems work flawlessly in both sizes and have taken the drama out of film processing for me. There's no more wondering if you got the film loaded right, or if your favorite negative will be ruined. It's a sacrifice I'm willing to live with.
