Thanks for the comments and suggestions. Do you have any information on the availability of the EAW or Recknagle claw mounts in the midwest, USA? Is there any way of buying these things without engaging in international commerce?

Mike, where are you attaching an aperture sight?

The rifle is still shown here: http://mannlicherschoenauer.com/used_guns.htm ; complete with its art deco stock.

Again, thanks for your interest and comments.

Tom
