It might be easier to put new bearings and brushes in that old router than to find a new router that will fit in that over arm accessory. Bearings are not made by the tool manufacturer. Each has a number, usually on the side covers, that will allow you to order replacements from many baring sources. For brushes, taking the old ones to one of the better hardware stores that carry a wide variety of small parts should get you a close match to the originals, but you may need to file one edge to achieve the perfect size. Filing a brush is easy, since the carbon is soft, but the job is very messy since the black carbon filings will make you look like a coal miner if you aren't prepared. A vacuum cleaner hose held close enough to catch the filings is the best way to minimize the mess.
If your router needs more than bearings or brushes, your next option will be to try to find a router with a motor that is the exact same diameter as this one, so it can be clamped in the accessory bracket. Another option to consider is how to modify the accessory to fit a new and readily available router.
I think your original router might be a Stanley and they quit making routers and supporting the ones that they had sold many years ago. To me, the design looks something like routers that were being made in the 50's and early 60's.
