What you are getting is a cleaned and reassembled sprInkler with original paint (did derust, but rerusted).  See photos for what sprinkler looked like before and after, first one and last five for the after.

Axle pin and bottom retaining plate were painted and replaced most hardware with new.

Tried unit and was leaking from lower bearing, so ordered and installed a new style bearing with internal and external O-ring for better sealing.

Will put original parts with unit for purchaser if requested.
