Picked up this flex adjustable last spring or so at a sale. It was sold as choice from about 10 adjustables sitting on a table. Can't remember if I got first choice but I know I paid $3 for it. Could have gotten it cheaper maybe but it is such an odd ball I didn't want it to get away. It was rough, locked up and rusty but a little time in Evaporust and it is good. I have never seen one before .
