These are all being sold for parts only, although a couple in the top row may work. if you have enough pressure, no guarantees though.  The ones in the second row, need the bottom section replaced. I have had these in the shop since the 1970s. I used to rebuild all my sprinklers, but not any more. Time to move on and let someone else have the enjoyment. Most all in the second row appear to be in fairly good condition, minus the bottom section.(bearing nipple, bearing sleeve, and associated parts).
