Looking for a RN Leading Wireman Badge

[brimacombe]

Good morning to you all! I'm hoping someone just might be able to point me in the right direction with this one...

I'm trying to track down an example of the Leading Wireman's arm badge (crossed torpedoes, star above and L below) to complete a frame (of an individual's medals, photo etc).

I've been looking on and off online for some time now, and so far no luck!

Thanks, as always!
