Where to start looking for HKS-RGA shoulder title

[TomPC]

Hi All,

I'm hoping to find a Hong Kong Singapore Battalion, RGA shoulder title but do not have a clue where to start. I've exhausted the internet, poor thing.

Where would you start looking for something like this? Anyone know anyone who specialises in either artillery insignia, colonial insignia or widely across all types of shoulder title?

This unit was part of the British Army so I presume it's OK to post in this sub-forum.

Thanks

Tom
