I found this in one of my crawl spaces mixed in with a pile of galvanized pipe and the big inserts that came from a converted coal boiler I assume. You know, the big iron ones that slide into the large passages.
Anyway, it appears to say Rich Fin and 30 gallons. There is some number before that but I can't make it out.
Does anyone know what this is?
