Thank You all for the sincere help in identifying this a/c and history. Here are some more photos (poor digital camera) to give add'l help. At USRA forum I was asked if any S/N in fuselage and nature of wing construction. No S/N is noticed and the entire wing is Nomex appears to have been vacumn formed. No spars or ribs are noted though surely some formers or ribs exist. Notice the indentation formed in the fuselage for the exhaust pipe. May give some clue. Also, appears to be Laminar flow wing? Thanks, Allen
