age of this vessel mouth, found near bronze ship spikes ?

[Trimbaker]

I went to the site I have been metal detecting, where the bronze ship spikes came from...I found this fired clay mouth of a large vessel. Any ideas on its age? Thank you for your thoughts. I hope you each and all have had good finds lately. George.

Heavy duty... Looks like the end of a turn of the 20th C sewer or drain pipe.

Yes, similar shape, but not glazed. I found it near a shell midden on the edge of a marsh island. When I look closely, I see that the rim is hand formed and pressed onto the lower part. I found a piece of pottery of similar material there which has the slight radius of a very large container. I would love to know just how old the piece might be, perhaps the next piece I find will help. : )
