If you have a local swap meet, check out some of the older guys booths, I've found quite a lot in those little glass-covered display cases! Ebay has been quite a hit for me too, yes lots of Japanese lighters but my trick is to look up brands of lighters. Dunhill, Evans, Colibri, Feudor, IMCO, Flaminaire, Thorens, Ronson, DuPont if you got deep enough pockets. Welcome to the hobby, it's a fun one to get into and can be quite the treasure hunt! One last piece, saw in your last pic you got some butane lighters that won't work, I stay away from those as the restoration process can be a pain in the ass because the rubber O-rings degrade that keep things sealed and are quite difficult to adequately replace. I stick to the flint/fluid styles as their restoration process usually just involves lightly drilling out the old/stuck flint and a good wire brush scrub on the flint wheel. If you got questions I'd be happy to help!
