1 & 2. i cannpt help with.
3. Shutgun is a quest reward. It can be used as a "material" but is it not compoundable. unless you are refering to the rifles then those are both already up and you can search and find them, they are manufactuarble..
4. Guard necklace also is a quest reward, it can be used as a "material" but it also is not compoundable.
The reason they both may be listed as "quest prop" is prolly due to them being quest rewards.. but i will try to edit them both.
Picklessssssssssssssssssssss!~
