I have two Mauser 66s, an 8x68S rifle with Schmidt & Bender 2.5-10x56 in claw mounts and a fullstock carbine in 30-06 with an LER 2.5x Leupold mounted "Scout Rifle" style. Both are early models from the late 60's. Both have DST and the early model safety. However, note the fluted bolt housing on the rifle.
