A friend has been appointed administrator of his late brother's
estate.
Among the items in the estate are 2 20' trailers with disassembled
airplanes in them.
One is some sort of Lycoming and the other holds a plane called a J3
Kitten.
Is there a newsgroup for aircraft enthusiasts similar to this one
where he can ask questions about the value of what he has and how to
sell them?
