You have a pre-safety, post-64 Model 94 Standard Carbine, with the changes/upgrades made starting in 1970 - a cast cartridge lifter/carrier ILO the previous post-64 stamped lifter, solid link pin(s) ILO the previous hollow rolled pins, and a better grade od walnut than 1964-1970 Standard Carbines.
IIRC, in 1983, the Model 94 action was changed to an angle-eject (M94AE) from the previous top-eject design, then agasin, later adding a rebounding hammer, and at first a crossbolt safety (CBS) then finally a top rang safety.
Some refer to those changes as "the death rattle", before US Model 94 production was stopped in 2006.
