155MM Howitzer part

[StevieV]

Dear WW2 enthausiasts,

Yesterday I went out detecting and found a lot of Howitzer parts. To this thread I uploaded a few pictures of a part I found. I have no clue what part this is. Google doesn't give me any information on the company name on the part "J.W.M.CO.18."

I was hoping anyone can tell me what (kind of) part this is.

Thanks in advance.

Greets Steven.
