Presently I am 1,200 miles away from this carbine, so not able to verify the initials on the mount. I will be back to it in two months time.
Perhaps an "AKAH" mount? I do like this mount: very solid and returns to zero when removed then reattached. I have one Model 1903 with Jaeger (US made) mounts, which are similar, they also work well for a return to zero when reattached.
