>>2926547If it takes 120 Film, that's available pretty much everywhere online and at some camera shops.
If it takes 116, 616, or 620, you can use a 120 roll in it with a little bit of MacGyvering:

Take a look at that other folding camera you have there, too. Brownie was Kodak's "budget" line of cameras at the time, and if it just says Kodak with no other branding on it, it might be a better camera than your Brownie. Or it might not be. I don't really know how much of a difference there was quality-wise between consumer-level folding cameras and consumer-with-a-little-more-money-level folding cameras back in the 1910s/20s, nor do I know the condition your grandfather kept one camera in versus the other. The only way to tell for sure is by taking some photos with them.
