No. I wasn't sure what it was. It has been there a long time as it has barnacles growing all over it. It is open like it has been cut open to show the internal workings. There are restricted military areas nearby so it probably came from one of thode years ago. Pembrey is one side of the river and several miles up the other side is Pendine Sands another restricted area.
It might be worth rescuing as an educational exhibit perhaps?
A photograph would maybe help identify it. 👍
