I had a look at them 3 years ago on behalf of a museum.They have been hangared for many years and at that time, except for the evidence of birds, the airframes were in reasonable condition.
At the time I suggested on this site that they were candidates for fire bomber conversion but was howled down by the local fire aviators telling me that they were no good, our trees are different etc.
I recently discussed this again with some persons that I met through another interest who are involved in aircraft fire fighting.I was firmly told that only small aircraft work here.I came away from that conversation a little mystified as their opinion seemed based on trials of 1 or 2 large aircraft not a fleet as is used elsewhere.Clearly the rest of the World is wrong on this topic.
