Now you confused me with the 900k rifles.
Would a ambidextrous safety from a 1950 EG work on a 1959 EG? I have to admit I thought most of the parts toward the rear stayed the same.
Like I said, I don't have access to a post mill 99E. But, I would be very surprised if the internals would be different from those used in the post 900K guns when they lengthened the rotor for the Winchester carts.
