Help on Rising Sun badges please.

[Madziro]

I am not a collector of Australian badges but have acquired a few rising sun badges and need some help please. My step son who lives in Melbourne gave me a copy of the excellent book The Lost Diggers by Ross Coulthart and this has started me looking for rising sun badges and info.

I have a cap and 2 x collar badges (KC) all marked Stokes and Son Melbourne with lugs on them. Will this be able to date them as WW 1 or WW 2? Is there any significance in whether a rising sun badge has a voided crown or not? Next question - does a slidered badge or lugged badge help to identify if it is WW 1 or WW 2?

I also have the attached small badges and have identified the one as for the Australian Commonwealth Horse as worn in the Anglo Boer War. The other one I have no idea as to its identity. Any help will be much appreciated.

Kind regards
