Twobob, the rings for those type of scope mounts are specific to each type of scope, therefore you would have to have a large collection of rings to be able to match up something that fits your chosen scope. Many of the rings from that era also 26mm which was a popular size then. Rings and bases can be custom made but are a lot of work and therefore expensive. They are however very strong and return to zero perfectly if made correctly. They are also very interesting and unique and fit well with the other unusual features of the Mannlicher Schoenauer rifles.
