Cool, I would have guessed it was a few years later. So my K Joe is from the final year of the wire legs. So the current leg style which appears to be the 5th style seems to be the longest running version, then. Original unconnected thin legs of the '50s-early '60s, then the thin wire legs that "hook" together at the bottom of the 1960s, the folding legs of the '70s-early '80s, the early mid 80s wire legs and ash pan and the "modern" style. Now for the question, which of the 5 are the most/least stable? I only have the last 2 versions, they seem stable, but how did the others hold up?
