WW2 M1 helmet and liner ?

[aghsmac1]

I recently bought the following M1 helmet which I consider to be a WW2 model. Please confirm me, indicating a possible manufacturing date.
The shell has a front seam without stampings (probably internally it's repainted and the stampings are covered) and in front has a supposed stenciled badge. if anyone considers it to be a badge and can recognize it please let me know.
The liner has a stamp of W (Westinghouse?) and possibly numbers that I can not read.
Thanks in advance,
Aghs

WW2 Shell made between oct43-nov44 and liner is pre oct 42.all components are ww2 vintage except paint on shell which is obviously postwar.

+1 to Jake. Seems untouched since the 50s era paint job though. Nice set
