I believe this is the same as the current Additional Safety Plate 60 (Brown) for Okutobira and Doors Woody. I've attached images of the instruction manual, so please check if the specifications are the same as what you are looking for. The plate is approximately 60cm wide. I purchased this on Mercari in 2021, and it was almost new. There are some minor scratches, but it's relatively clean as it was hardly used.
