What's funny, is that when i was chasing down parts, I found a coal boiler service guy who's shop was just a few blocks from where my AA boiler had been rescued..
I went to buy some parts, and told them about my AA from just down the street, he laughed and said that it definietly needed a full rebuild, that it had been under water at least 4 times that he knew of,
The owners had called him only when they had to, and only to bandaid it back together.. I had no doubt about his comments, my boiler was a testimony to bandaided repairs.
These are TOUGH units and with a little TLC, they should last about forever, mine is one of the first AA260's, according to Axeman's. Built in 1950, the boiler is two years older than ME !! I wish I could rebuild ME like my AA got rebuilt !!
