Here is the bolt face there are no front locking lugs just two rear ones. But for a .22 its not necessary.
Here is the safety/decocking knob. It is similar to a mauser in that it is rotated to the 12 o'clock position for safe and the 9 o'clock position for fire. It also serves as a decocking knob to ease the firing pin forward if not firing the rifle. On a side note the trigger is very very smooth and very light.
Here is the rifle next to my M38 . The Wz. 48 is about 4 inches longer then the M38 but they are both around the same weight. The barrels are also about the same thickness, and sights are the same except the Wz. 48 sights is only graduated from 25-100 meters. Overall the rifle is in excellent condition with just two small dings and some minor bluing wear. I will be going to the range hopefully monday to shoot this rifle an will update accordingly. This rifle will make a fine addition to my rim-fire and milsurp collections.
