I have a Squash Rockets going spare. Going to bed right now, but if I remember I'll add you in the morning.
I also have spare:
Boo Balloon (Uncraftable)
Heavy Soul
Exorcism x5
Putrescent Pigmentation x2
Die Job
Spectral Spectrum
Sinister Staining
Pyro's Muffled Moan
Eerie Crate
Anything other than the balloon or the soul I'll trade for just a weapon. Balloon is worth 2 reclaimed according to backpack.tf, the soul I haven't even checked because I'm hoping to just trade it directly for a Demoman Soul, which is the one I don't have.
