The newer models, post war, were more common with silver bolt handles, in 30-06 and 270. They can be found but only pop up sporadically.
The Leupold Adjusto mount is great, but you need to find the mount and rings, both of which are proprietary designs. It’s a bit of an odd system to use, but does have a 26mm ring option so older, period correct (post war to mid 70’s) scopes can be used. When the base is mounted, use of the iron sights is obstructed. These crop up on eBay every so often, but are expensive. Williams also made a side mount, as did Pachmyer. Same challenges apply. In finding what you need.
