It is definitely an SR102. It's black. It was supplied by Sky in June. It says "Model: SR102" in very small blue print adjacent to the ac input. I can see this through the clear plastic wrapping. I'm reluctant to remove the wrapping, which would be necessary to power it up and see the UI, because I want to sell it as "BNIB".
I only know that there are variants of the SR102 because I checked what they were selling for on ebay. I think I can honestly describe it as "latest", but if I have to unwrap it and power it to establish the exact model, a buyer might not agree that it's "BNIB".
