Your metal roller the length of a 120 is 620. Indispensable if you want to use 120 film in certain Kodak cameras (620 was originally Kodak's lock-in format -- same film as 120 but the spool was smaller, so the Kodak cameras would only take 620 film).
Yashica had a 135 adapter for at least one of their models (the 635); as I recall, it was standard 24x36 frame (it adjusted the film advance as well as masking the film gate). Made a nice portrait camera that way. Rollei made one of those too, for one version or another of Rolleiflex or Rolleicord. Handy for travelers, as it was often easier to get 135 film than 120, almost always cheaper, and you could fit more exposures in a small bag by using the compact 35 mm film.
