As the title suggests, I am trying to work out what uniform is being worn in this photograph.

This is my great-great-great grandfather, who fought for the 38th in Crimea, but I think, though I'm not sure, he ended up in the Leeds Rifles.
Any light you would shed on this would be great, including the rank (possibly staff sergeant??) and colours.
And if you have a really keen eye and can identify the medals (one of which should be for Crimea), that would also be great.
Thanks
Phin
