Thank you Pete!
Not much info to find of this cartridge, but I did find a small note in the pages from IWM with reference to an old book.

I found some more as well: As in .500 Tranter and .500 Webley.

I think @Mel wrote something on these recently?

Yes, I did something on a large-caliber British handgun cartridge but it was the .577 revolver round, a little bit larger than the .500.
