Scottish Rifles - help needed !

[gurkharifles]

I hope someone on the forum can help me. My Godson is 18 next year and he's become increasingly interested in his family's history. I've told his parents that for his present I'd put together a frame of his Great Grandfathers medals and insignia. So here's what I know: Private John Bulloch - Scottish Rifles ( I assume that's the Cameronians ? ) No. 1672. I have a photo (attached) and I have his named Victory medal. - Wounded at the Somme.

Questions:
1) Can anyone tell me what medals he was entitled to? ( Family history think it was 3 and they were split up amongst the family?
2) Would the cap badge have had a tartan backing ? ( Douglas ? )
3) Is the cap badge I'm looking for KK631 ?
4) What shoulder title would have been worn ? Blackened SR ?
5) What are the insignia on his sleeve ?

Many thanks in anticipation - and I promise to post a picture of the finished project. Tim
