forgotten weapons?

Have you seen these sprites before? I wonder if these weapons were in the game at some point or if they still exist.




the sprite is from the fpg file. I can't say if it's original or not, maybe someone edited it and added it to the file idk.

I believe one of the weapons might have been a shotgun.  I have examined its related graphic labels when I used FPG EDIT 2009 and I do not think they have ever been utilized, even via modding or hacking.
