Rising Sun Badge basic information requested

[At51]

A small collection of insignia, that belonged to a WW1 British Army soldier, in the possession of his family continuously, includes a few items (some damaged) unrelated to units in which he served. One is a Rising Sun badge. It is believed to date to WW1. I knew nothing about this badge but Internet ‘research’, including a quick look through this subforum, indicates the long history of the badge, its multiple makers, manufacture in the UK and in Australia, and its use in more than one capacity. The most recent “custodian” of the badge has provided photographs.
We wish to know of anything which might indicate an origin other than WW1, what type of badge it is and any other information that may be gathered from it. The hope is that accurate information will help engage the following generation. Any help will be gratefully received.

A nice badge and certainly genuine. It is one of many unknown maker variants, worn as a collar badge and as an officer cap badge. I have had a similar one for years and have always thought it was WW1, probably British made. Unfortunately without a maker mark it is impossible to be sure.

Thank you kingsley for your very helpful reply.

I would concur with kingsley on his comments. Without a maker's mark, difficult to date. I would just point out though that the small, collar size badge, was worn on the service cap by all ranks, not just officers, in WW1. Mike

Thank you mojob 123 for your reply, especially as to the use of the collar size badge.
