Nozzle ?

[Burnt Chimney]

A few weeks ago I dug this at an old homesite near Liberty Hill SC. I think it may be a nozzle for something not really sure though. It has what appears to be a check valve in it and a thin rod attached through the center. It's mashed but there is some free travel back and forth. I am leaning towards bellows tip but I would like a comformation. Thanks for the look

Hummmm , if it was a bellows tip wouldnt it be hollow on the inside ?

How about part of a siphon pump of some sort?
