Pebble dash stones The Original Plasterers Forum - The

I need to pebble dash a patch which looks bad, so I need to buy the same stones like the rest of the wall, I have looked a little bit around but can't seem to find an exact match, my question is can anyone have a look at the pictures below and recognise/ identify the stones & where I can buy them?
