I cant speak to the capabilites of the Madge device. However, Cisco routers do support source route translational bridging, which in effect does media translation. One quiestion would be, is there any routing in the network right now ? If, for example the 3920's were on subnet a, and the 4006 on subnet b,
a router with both token and ethernet interfaces would do the job.
here is a link to the SRT stuff. Also, depending on your applications, Data Link Switching might be a player.
Why do you need a migration period? The network is small enough to replace overnight with a bit of effort and planning.
In any case I would advise against SRT if you can possibly avoid it. Why do you need to bridge the two networks, rather than route between them? This would be preferable as long as you are not running any non-routable protocols.

in the network to know of every link and OSPF speaker in the entire
network. From this picture each router independently runs the Shortest
