Just because it was mentioned on the previous page, I saw one of the "new" XP-70's at Zellers the other day on sale for 8 bucks, so I picked one up for old time's sake, it being my second Super Soaker. I noticed this on the back of the box:

I love this colour scheme, was the 70 ever produced in those colours or is it just a prototype mock up? Of further interest on both this version and the actual blaster is the mixture of logo styles in the decals; the "final" version of of the original Super Soaker logo appears along side the second wave (if I'm recalling correctly) XP-blaster logo.
And just to keep the thread on topic here's a picture of the new SS-50. My apologies for the absurd background and trippy lighting, I live in a nerd cave.

Both of these bring me back, although my interest in water guns only picked up after the XP series had replaced the original ones. I miss those days dearly when the sunlight hits the trees just right in July.
