If you remove the safety and look at the cuts in the end. That is what locks and unlocks the bolt. If you have one make in reverse it will be left handed.
Other than that I would check Midway or Brownells for after market safeties for custom rifles.
I think there are some made for 96 or 93 actions. I think I have seen a couple of replacement parts that allow you to use a wing safety like on a Win M70. But it may only be for the 98 actions. There are some that are set up for scope mounts and are very low.
Good luck in your hunt.
I find it best to get the catalog and look, rather than search on line.
Or go to your favorite gun shop today and ask to see his copies. You will be able to order it from them and not have to wait for the catalog to show up. I had to lend my copies out to others as I start looking and new projects come to mind.
