Might be worth contacting Walt Shiel (
http://www.cessnawarbirds.com) to see if he has any leads on one.
There is one... not sure if it is an original T-41... at Broulette Aviation Training in Nashua, NH (
http://www.flythebat.com). It has been there for a while and flies rarely. Looks to be in great shape... they might want to sell.
Best of luck on your search!
