I've been going through a collection of military headgear and identifying the shells and liners to the best of my ability. I've come across this liner that I can't identify in the slightest. It is currently in a Canadian steel mark II 1942 shell produced by Canadian Motor Lamp Co. of Windsor. The shell still has the bales but no chinstrap and is in great condition, possibly never saw much combat.
The liner is not like any one I've come across or can find online. I have been unable to identify the manufacturer's stamp, though it looks super familiar. It's not an original liner, but beyond that I'm stumped. This liner has its own bales and a chinstrap. Instead of rubber bumpers it has steel pressure ones. I've attached some images of the liner below.
Any help identifying it would be much appreciated!
