I think it would be a good idea for them to update their website with some new material. For starters, they could acknowledge the passing of Mr. Barnett (a caption beneath his photo if they want to keep that on the home page, J. P. Barnett, 1941-2011, with the correct values of course.) And then add some pages showing the new owners and staff at work on current products.
This would demonstrate that there is still life in the company whereas the old website unchanged implies no one is keeping it up.
