Unmarked vintage cast iron well pump novelty planter - this is so cute! The pump body and water trough are made as one piece, with a separate handle attached with a nut and screw (which I don't believe are original to this piece though does the job).
This is painted a dark green color, with the bottom of the pot painted red. Nice patina, this has a little age to it. It's about 4" across the planter pot, pump stands about 7 3/4" tall.
