I picked up an older sunfish today at a Boy Scout camp in New Hartford Conn. possibly from the late 60's the plate with the hull # on the deck was removed but it looks exactly like the "66" that I have. They gave me five old style rudder tiller set ups and one had a hardware set up I've never seen before, holding the rudder blade to the thingy that snaps onto the transom. I think thingy is an official term after seeing Signal Charlie " thingy and then unthingy" a clip on the Catfish, Smedley. Anyway, I got a picture of it, I think I'm going to clean it up, sand any varnish the newer style blade and mount it on my 1966 sunfish that just got a new blue paint job.
