I have a folder I would like to try. I heard I can use a roll of 120 in the camera if I get a 620 take up spool or do I need to respool and get two 620 reels.
Best to use two 620 reels and respool on to one - Got a Box Brownie myself that takes 620 spools, and the standard 120 reels will not fit in either end.
The 620 spool as the take up spool works in the old Brownie Hawkeye. You can find the 620 spools on eBay, however you might make the rounds at Goodwill and pick up an old camera with either one or two spools still inside.
