I think I might take you up on this generous offer to help source something suitable. If you see something for sale please let me know, and perhaps assist with the re-posting to Australia. Reimbursement for any costs of course.

My main provision is the scope and mounts need to work as intended, as the rifle will be a user rifle in my hands.

The Leupold scope might be kept for use anyway, or find a new home on my Anschutz .22 which needs a smaller scope to better fit the tiny rifle. In any case after trying out the Leupold I already had in mind a second for the Anschutz.

Thanks for your comments regarding a possible alternative to restoration which to me sounds just as good. One reason for my query was whether a restoration as outlined would affect its value.
