In my case, I'm not sure when it's vintage and when it's just plain junk! Being an opportunist and cheap, I do use things and re-purpose them for plant containers. The toolbox looks pretty good. I think that's mostly sedums and echeveria type plants showing. Makes me think an old tackle box would work pretty well. So many have that attached upper shelf made into compartments of varying sizes that could be put to use. Looking at the pinterest photos made me think an old hay hook would make a good hook for hanging a container - stout and you probably would even have to alter or damage it to put it in use.
Here's a photo showing two I've put to use:
In the foreground is Kalanchoe tomentosa 'Chocolate Soldier' in the old enamel pot found in a trash dump. Complete with a bullet hole on the other side. I really like this plant in this container. The bottom is corroding out and I have to see if I can repair it to keep using it. I didn't try this year. I hardly ever give the tomentosa water and I'm afraid to bother it because it quickly taught me to leave it alone soon after I acquired it the first time and promptly killed it without any effort. In the background, the Sansevieria is growing in an old 12" diameter galvanized funnel. It has worked well for a hanging Sansevieria. Old colanders would probably be good as well. On using metal, I think it might be a good idea to coat them on the inside before planting in order to slow down corrosion. I haven't done that, but I do plan to when I re-pot these.
I just realized that's there's the old light fixture I dragged out of the trash container at the feed store showing in the photo. I rigged it up as a plant container and it can be seen sitting on the top of the stovepipe section. Those stovepipes have worked really well. The two I'm using were just lying around and were free, but they've worked well enough I've considered getting a couple more. Or maybe really wide diameter PVC pipe would work if it comes in a wide enough size and isn't prohibitively expensive
