B&D for beading along a curved edge

ovenledg said:

When I was an apprentice I worked in a shop that had a B&D router that we used to to put a bead along a curved edge. A bearing would follow the edge and it had a cage-like piece that acted as a depth adjuster over the bit. It was approximately the same size as a laminate trimmer. Does anyone know what I'm trying to describe and have any information about it? Thanks.
