Another remark, in post #1, the second picture reel-2.jpg that is labeled "135" is also unusual. A 35mm reel will usually have thinner wire and many more turns. Typically a 120 reel has about 5 usable full turns and a 35mm-36 exp reel has about 9. The reel-2.jpg reel has about 6 full turns, meaning that either it's only for 20-24 exposure rolls, or the height is different and is actually for 127 film. I have not seen a 127 steel reel, but supposedly they exist.
