"...older generation that knows and collected these is fading out or losing interest in them..." that's equivalent to what I stated.
I doubt anybody collects butter churns, horse shoeing equipment, and canning equipment. That was such a 70s thing.
It's getting difficult finding people that still do sewing or seamstress work.

Imagine having a Eureka mighty mite collection. lol. But, yeah, it makes sense.
It's weird to think that the Hoover spirit canister maybe too old for young collectors.
