What a great weapon.  Maybe not great for it's power, but great for the reaction it caused.  This gun literally created the water war concept.  It introduced the 'larger gun than I have senario' since most other guns around this time were just plastic squirt pistols.  I was happy I had found one, but I had a lot of work to do.

This gun holds about as much dirt as it does water

After knowing that my firend had a really badly busted up SS-50 in his backyard, I went back there to look for broken off pieces, including most of the barrel.   I was looking around and I saw it, the barrel sticking ap a little bit from the ground!  But when I went to pull it out, something amazing happened.  A whole gun appeared!!! I had pulled up another SS-50, this one being in much better shape.

This weapon was dirty, really dirty.  Well, what else could I expect from it being in the ground for a countless number of years!   When I pulled this gun from the ground, it still had half a tank of water in it!!!!!!!!!!!!

This is a picture of the gun taken apart.  This picture was taken after I had cleaned it in a shower for about 20 min!  I would clean it, and more dirt would just come out of it!  Anyway, I was surprised at the simplicity of the weapon.   I admire the simpler weapons, they are easier to work on and usually less prone to breakage.  The whole trigger setup was basically a piece of plastic pinching of a clear tube, holding in the pressurized water, leading to the barrel.  It was held there by a leaf spring. 

I cleaned up each individual part, and got the gun back together.  I did several testings trying to get water pressure, I thought there was a problem with the seal when water started leaking out of the pump chamber, but then I remembered!   Single tank guns(water reservoir and pressure chamber combined)  don't pump water, just air!  So there was a problem with the one way valve.  This I feel is somewhat typical of older guns, especially if they have not been used in years.  So I kept pumping and re-broke the gun in, and it started working pretty well!

This is a picture of the gun , restored.  Looks a lot different from the first picture!  I had to saw off the trigger guard, because half of it was missing in the first place, other than that, and a little fading, this blaster is in great shape!
