Maybe Bruce Bertram,a obsoletie casemaker in Victoria.
The kangaroo should give it away.

Length, head and rim diameter could help identify what case it is based on.

Yep, sav300 had a great idea.
I went to the Bertram Brass website, the headstamp shows on their home page in the background picture, but I couldn't find info about the case in their picture. Their .375 caliber options show the same piece of brass, none that seem to make sense to me. They do have a button that says "contact".
To get to the page listed below, go to their site and click on the "shop" button, hovering over it won't get you all their options.

What IS the case head diameter? Looks like a small artillery shell compared to the .375 H&H. I have a .375 H&H so I have a feel for how big it is. The H&H rim is .532" and the Rigby is .590". That BB case looks like it's almost twice the diameter of the H&H.

Ori, its a 375 Chey Tac case, .635 base dia, about 3.00+- length. I got a bunch of them to convert to 408 Chey tac from a supplier in Montana. check the case mouth to see if its actually .375 or .408 ?? Might be one I loaded here locally.
