I know this thread is kind of old but I have 356 air master that is setup with yellow but has less then 100 solves. I will re-lube it just to make sure that it is still good. I dunno how much shipping will be, but I will sell it for $20 plus shipping coming from the west coast of the United States. I can send it with everything, the box, tool, springs, booklet (cool poster) etc.
