Bren gun tripod harness

[chris vickery]

Was wondering if any of our resident arms buffs might know anything about the harness or webbing that was utilized with the Bren tripod?
I picked up a harness and it appears to attach where it would logically fit, but this webgear makes no sense. Are there any pictures out there of it being used in the field and with who? Mine is marked as being Brit.
Other than simply acting as a carrying handle of some sort, I would pity the man who had to wear it on his back, if indeed it is a web harness???
