So I found a guy selling two CPS 2100's on ebay:

Looks legit? Maybe. But he is also selling four mini CPS 2100's. The right color, but not the right cap, pump, or size. (8 inches long!)
Knowing Hasbro never sold mini CPS 2100 water guns, it makes me question the yellowed full size CPS 2100's.

Then again, I have seen a cps 2500 so dirty/faded that it was brown instead of grey, and one that was orange+ grey.
Anyone heard of knock off yellow 2100's before?

Those are just regular 2100s that are very faded. Hasbro did release a mini 2100, I have one at home. It's not keychain or pen small, it's a little bigger than that, remind me in November and I'll take a picture of it.

Those actually look really cool…

They look real to me.
