New guy here. I'm not a BIG cast iron collector by any means. I Inherited some iron a few years ago that was a bit crustified. I found that I enjoyed cleaning and restoring the iron, so I've slowly begun "collecting."
Of course, for me, that means finding a piece at a thrift store, yard sale, friends garage, etc. I don't fancy newer pretty iron. At least not to buy. The grimier, the rustier and the crustier the better for me. I also enjoy trying to figure out WHAT I've cleaned. Sleuthing about for answers in regards to makers and years of origin is a pretty fun way to pass the time.
Finally...
I am NOT a cast iron snob. I couldn't care less about what's "rare" or "vintage." I just like finding, restoring and gifting out iron to those I know will appreciate the effort. They may hang them on the wall as decoration or throw them in with their camping goods. Either way, it makes me feel happy.
CHEERS!
