I try to make sure each of mine is different in some meaningful way. I don't always succeed at that though. Some I buy because they were cheap and I know I could restore them. Some I buy just because I think they look good. But yes I too am reaching a point where I have to ask this of myself.

In my mind I'm creating a museum. I have them categorized into displays or exhibits that I could demonstrate some set of differences or similarities or progressions. But I don't have a museum. I'm trying to work with my local library to do displays (as well as a type in) and that's why I have the YouTube channel, to be the eyes into my collection even if people can't walk into my house. I do have some plans for some more exhibition style videos, so far most of mine are repair, but I do want to make these comparisons too.

Or maybe I just have too many, who can say
