Bren multi tool identity

Hello all! Just got word back from the Jedi master of commonwealth arms Mr. Ian Skennerton . Seems that the multi tool was produced by Norton Toothell and Co. 16 Barrack st. Sydney. You can see their mark on the small parts tin also in the Slazenger Bren wallet. They were a subcontractor for Holden/ General Motors . Cheers to all me Mates in Oz!

Hi woodsman, thank you!
I posted a thread in June last year. I did keep trying but had no luck.
My brother worked at the Lithgow Factory and neither he or his mates could assist.
Thanks Denise
