Can Anyone Advise on the Make of This Airsoft M1918a2 Bar?

[Westinghouse]

I’m picking this m1918a2 airsoft bar up from a mate of a mate (not from a scammer!) but he doesn’t know the make of it. 
 

is anyone here able to identify the make from the below photo? Trying to find out more about it 
 

cheers in advance

Looks like a ACM bar. Similar to in the link.

There are several brands but they all appear to be the same OEM.

Cheers all - DerDer is right it’s definitely the ACM!
