It's a Kitchen Sync, and it looks like it has the genlock board installed too. Unfortunately, there aren't any of the external connection and control boxes pictured - it's totally useless without them. Could be worth checking with the seller though.
There are two black plastic units, the first with an LCD display and 5 push-buttons, and the second has 6 BNC connectors. Both are cables back to the two ports on the rear of the kitchen sync card.
