This is a Kodak Brownie Hawkeye, one of the few 620 cameras that will work with 120 film provided you have a 620 spool for a takeup reel. There is enough room to just barely accept a 120 reel. Film with cheap plastic spools work best since they are often narrower. If one brand does fit then try another. Wind slowly and remember to cover the ruby window with a bit of black tape between exposures. Have fun.
