Eveo dual screen/monitor mount (Mortimers Cross HR6)
Bought this at an auction but its not quite low profile enough for my desk, also has some missing screws...however its an expensive piece of kit (£100+ on AMAZON at mo, screen grab added) so if someone's game I'm sure they could source a few screws. Does not come with setup manual but I googled it and there are manufacturers walk through guides readily available.
