Dino,
Thanks for the contribution; you've got a nice one. Say what you will about Australia's re-parkerizing, they did a good job of it and a good many of them seem to have been placed in storage immediately after the FTR, meaning they're in great shape.
To complete the entry into the database, can you describe the top strap and butt markings? And, please confirm that that is a "P" proof at the upper left of the frame. Are there also "P" proofs at the rear face of the cylinder and underside of the barrel? How about an importer's marking?
