I just bought a 602 at an auctuion for $50 - It was a gamble as I just stumbled upon it in the middle of the auction. I didn't have time to look it over.. turns out to be in very good condition. The side baffles are a little curved, but the box itself is in fantastic shape. It looks to be from the 70s - 80s era. I have a small ( 350 sq ft) bright unheated study that I use to tie flies. Hoping this will coax me out there in the winter. Anyone know of a place that sells those inner baffle plates? The reason I jumped on it was it came with the original manual and this really cool vintage round soapstone trivet, which by itself was worth the 50 bucks.
