Howdy folks!

I've got a brain puzzler for those who use Underwater Hideout. For the last week I've been collecting standard and unique weapons just to be able to say that I've acquired all weapons for the display walls. Each weapon, with a couple of exceptions, has been collected honestly. Meaning, through eliminating the named NPC carrying the weapon or reverse pick-pocketing. Since I chose Wild Wasteland I won't be able to obtain the YCS/186 unless it is through a mod. Bummer. I've looked high and low to find out what weapons go in the spots but haven't had any luck.

First is the Explosive Wall. There are two spots which I haven't been able to fill. Please reference linked image.

Spoiler:

Second is the Small Weapons wall. There is one spot which for the life of me I haven't been able to find an image for what is actually supposed to go there. Image linked for reference.

Spoiler:

Any help would be greatly appreciated.

You seem to have all of the Unique vanilla explosives on the top image, and unique small arms in the second. The only thing I would say is get the unique DLC weapons aswell and if those don't fit then they are just extra spaces.
